I am trying to format a double value to two decimal places in a struts <html:text> tag. ex)
<html:text property="freight" size="9" maxlength="9" />
the value inside freight is a double for example $100. When it displays, it shows it as 100.0, not 100.00 (like I want it to).
I would like to display all double values to two decimal places but the <html:text> does not have a format property.
Could someone please help?
You can use <s:text> tag to do it.
Add a formatting entry to a .properties file (probably package.properties)
format.twodecimalnumber={0,number,#0.00}
Then in your view (JSP) file, the following code can be used for displaying a formatted number
<s:text name="format.twodecimalnumber">
<s:param name="value" value="53.3" />
</s:text>
If you want the formatted number to be displayed in an input textbox, you can wrap the above code inside a <s:textfield> tag. Like so -
<s:textfield>
<s:param name="value">
<s:text name="format.twodecimalnumber">
<s:param name="value" value="53.3" />
</s:text>
</s:param>
</s:textfield>

I am trying to edit an XML file with Wix. I am using the WixUtilExtension bundled with Wix 3.7. The xml file is a settings file created in Visual Studio 2010 for a C# application. In this file, I am using an element which is used to store multiple string values in an array. This is the content of the unaltered settings file:
<configuration>
<applicationSettings>
<AppName.Properties.Settings>
<setting name="StringArray" serializeAs="Xml">
<value>
<ArrayOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
</ArrayOfString>
</value>
</setting>
</AppName.Properties.Settings>
</applicationSettings>
</configuration>
I want to add <string> elements to the <ArrayOfString> element in this file. One way to do this is by using an <XmlConfig> element from the wix/UtilExtension namespace. I have added this element to the component which holds the config file like this:
<Component Id="ProductComponent" Guid="$(var.ConfigGuid)">
<File Source="SettingsFile.exe.config" KeyPath="yes" Id="FILE_config" />
<util:XmlConfig
Name="string"
Value="My value"
File="[INSTALLFOLDER]SettingsFile.exe.config"
Id="String1"
On="install"
Action="create"
Node="element"
ElementPath="/configuration/applicationSettings/AppName.Properties.Settings/setting[\[]#name='StringArray'[\]]/value/ArrayOfString"
Sequence="100"
/>
</Component>
This results in the addition of one <string> element to the <ArrayOfString> element. To add another <string> element to the settings file, another XmlConfig element has to be added to the <Component> element of the setup project with a different Id attribute and a higher value for the Sequence attribute like this:
<util:XmlConfig
Name="string"
Value="My second value"
File="[INSTALLFOLDER]SettingsFile.exe.config"
Id="String2"
On="install"
Action="create"
Node="element"
ElementPath="/configuration/applicationSettings/AppName.Properties.Settings/setting[\[]#name='StringArray'[\]]/value/ArrayOfString"
Sequence="101"
/>
After installation of the msi, the <ArrayOfString> element in the settings file looks like this:
<ArrayOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<string>My value</string><string>My second value</string></ArrayOfString>
I have found out that it is possible to set the Value attribute of an <XmlConfig> attribute to the value of a property like this:
<Property Id="STRING1VALUE" Value="My value" />
<util:XmlConfig Value="[STRING1VALUE]" ... />
This is good. I would like the user to be able to add multiple values in the installation process dynamically so that a variable amount of <string> elements can be added to the settings file.
My first approach was to use a <?foreach?> statement like this:
<?define values="My value;My second value"?>
<?foreach value in $(var.values)?>
<util:XmlConfig
Name="string"
Value="$(var.value)"
File="[INSTALLFOLDER]SettingsFile.exe.config"
Id="String$(var.value)"
On="install"
Action="create"
Node="element"
ElementPath="/configuration/applicationSettings/AppName.Properties.Settings/setting[\[]#name='StringArray'[\]]/value/ArrayOfString"
Sequence="101"
/>
<?endforeach?>
There are a few problems with this approach:
The foreach statement uses a preprocessor variable which cannot be set to the value of a property.
The value of the Sequence attribute stays the same.
I would like the user to store the values for the string elements in a Property which separates the values by semicolons and then parse them in a foreach statement like this:
<Property Id="VALUES" Value="My value;My second value" />
<?foreach value in [VALUES]?>
<util:XmlConfig
Name="string"
Value="$(var.value)"
File="[INSTALLFOLDER]SettingsFile.exe.config"
Id="String$(var.value)"
On="install"
Action="create"
Node="element"
ElementPath="/configuration/applicationSettings/AppName.Properties.Settings/setting[\[]#name='StringArray'[\]]/value/ArrayOfString"
Sequence="101"
/>
<?endforeach?>
This throws the following error:
The util:XmlConfig/#Id attribute's value, 'String[VALUES]', is not a legal identifier.
Identifiers may contain ASCII characters A-Z, a-z, digits, underscores (_), or periods (.).
Every identifier must begin with either a letter or an underscore.
Is there any way I can create a variable amount of elements with the XmlFile or the XmlConfig element? Is the only solution to this problem a CustomAction?
Based on Rob's answer, here is my new approach to adding multiple elements to an XML config file with Wix. I did not want to write C++ code, that is why I used DTF in my CustomAction.
I am going to describe how to turn a string containing multiple elements using a delimiter into multiple XML elements.
First there needs to be a property in the setup file containing the delimited string.
<Property Id="STRINGARRAY" Value="string1;string2;string3" />
This property could be populated by the user in a dialog, of course.
Next, a CustomAction has to be written. To make use of the DTF, a reference to the Microsoft.Deployment.WindowsInstaller.dll has to be added to the C# CustomAction project. The namespace Microsoft.Deployment.WindowsInstaller should be included with a using directive in that project. My CustomAction looks like this:
[CustomAction]
public static ActionResult Insert(Session session)
{
string strings = session["STRINGARRAY"];
string[] stringArray = strings.Split(';');
Database db = session.Database;
View view = db.OpenView("select * from `XmlConfig`");
string xpath = "/configuration/applicationSettings/AppName.Properties.Settings/setting[\\[]#name='StringArray'[\\]]/value/ArrayOfString";
for (int i = 0; i < stringArray.Length; i++)
{
string id = String.Format("String{0}", i);
int sequence = 100 + i;
string value = stringArray[i].Trim();
Record rec = new Record(
id,
"[INSTALLFOLDER]SettingsFile.exe.config",
xpath,
null,
"string",
value,
273,
"ProductComponent",
sequence);
view.InsertTemporary(rec);
}
db.Close();
return ActionResult.Success;
}
Here, at first the Property StringArray is read into a local variable which is converted to a string array. The following line establishes a connection to the current database used by the installer. A handle on the table XmlConfig is created, which is the table where the XML elements are added to. To insert the right values into that table, it is best to create an installer file which contains such a table and then take a look at that table in an editor like orca or InstEd.
In the xpath, backslashes have to be escaped by using double backslashes. The id variable holds the name of the temporary record, using a simple string and a number works flawlessly. The sequence has to be incremented for each element. I could not find any documentation on the values of the flags column, but I have found out that its value is set to 273 for elements that are created and 289 for elements that get deleted.
Once the record is filled with the correct values, it gets added to the XmlConfig table by using the InsertTemporary method of the view object. This is done for each element found in the delimited string.
A problem I have come across is that this CustomAction fails, if the XmlConfig table does not exist. To counter this problem I have added the following code to the setup file, which adds an element to the XML file and immediately deletes that element. I guess there could be a cleaner solution, but this was the easiest one for me.
<util:XmlConfig
Name="string"
Value="Dummy"
File="[INSTALLFOLDER]SettingsFile.exe.config"
Id="DummyEntry"
On="install"
Action="create"
Node="element"
ElementPath="/configuration/applicationSettings/AppName.Properties.Settings/setting[\[]#name='StringArray'[\]]/value/ArrayOfString"
Sequence="1" />
<util:XmlConfig
On="install"
Action="delete"
Id="DeleteDummyEntry"
Node="element"
File="[INSTALLFOLDER]SettingsFile.exe.config"
VerifyPath="/configuration/applicationSettings/AppName.Properties.Settings/setting[\[]#name='StringArray'[\]]/value/ArrayOfString/string"
ElementPath="/configuration/applicationSettings/AppName.Properties.Settings/setting[\[]#name='StringArray'[\]]/value/ArrayOfString"
Sequence="2" />
Finally, the CustomAction has to be added to the setup project. By adding a reference to the CustomAction project in the setup project, the location of the binary can be specified like this:
<Binary Id="XmlCustomActionDLL" SourceFile="$(var.XmlCustomAction.TargetDir)XmlCustomAction.CA.dll" />
The CustomAction has to be executed immediately, otherwise it won't be able to access the session variable:
<CustomAction Id="CA_XmlCustomAction" BinaryKey="XmlCustomActionDLL" DllEntry="Insert" Execute="immediate" Return="check" />
<InstallExecuteSequence>
<Custom Action="CA_XmlCustomAction" Before="RemoveRegistryValues" />
</InstallExecuteSequence>
To determine the right position for the CustomAction in the installation sequence, I relied on this article by Bob Arnson.
Yes, this is possible but if you want to have this determined at install time then the preprocessor is not an option. The preprocessor executes during the build process.
To get what you want, you'll need to write another custom action that takes the arbitrarily long set of user data and adds temporary rows to the XmlConfig table. The WcaAddTempRecord() function in src\ca\wcautil\wcawrap.cpp can do the work. The src\ca\wixca\dll\RemoveFoldersEx.cpp is a pretty good example of using WcaAddTempRecord() to add rows to the RemoveFile table. You'll want to do similarly.
I want to know what is the suitable replacement for this line.
this.__LZtextclip.text
I am using this to get the string present in the text node. This works fine in Openlaszlo 3.3 but in 4.9 and 5.0 it's giving a problem
I tried updating it to
this.sprite.__LZtextclip.text
And i am getting an error:
79: Error: Access of possibly undefined property __LZtextclip through a reference with static type LzSprite, in line: Debug.write(this.sprite.__LZtextclip.text);
Any idea why this problem is happening?
If you are trying to access the text content of a text field, why don't you just access the attribute text?
<canvas>
<text name="sample" id="gRead" />
<handler name="oninit">
gRead.setAttribute('text',"HI");
Debug.info(gRead.text);
</handler>
</canvas>
In OpenLaszlo 3.3 there is method getText(), which gives you the same value. Accessing mx.textfield in your code does not work for the DHTML runtime.
Edit: Added information regarding the stripping of HTML tags
The Flash Textfield class flash.text.Textfield provides an API to enable HTML tag content in a Textfield instance. There are two different properties, one called text, the other one htmlText. If you want to directly access the Flash Textfield object of an lz.text instance, it's a property of the display object of the lz.text instance:
// Flash Textfield instance
gRead.getDisplayObject().textfield
// Pure text content
gRead.getDisplayObject().textfield.text
// Formatted text
gRead.getDisplayObject().textfield.htmlText
You should be aware of the fact that Flash automatically adds HTML format to any textstring you set as content. When you do
gRead.setAttribute('text',"HI");
the textfield.htmlText value is
<P ALIGN="LEFT"><FONT FACE="Verdana" SIZE="11" COLOR="#000000" LETTERSPACING="0" KERNING="1">HI</FONT></P>
For the DHTML runtime, the text content is added as the innerHTML of a <div> tag, and there is no standardized API to retrieve the pure text content of a DOM structure for a tag with content. You could write your own function to extract the text content, or use JavaScript functions from existing frameworks - like the jQuery text() function - to achieve the same result for the DHTML runtime.
I guess the reason is that Laszlo started using the Dojo based rich text editor for text input with HTML formatting since OpenLaszlo 4.0 or 4.1.
The best approach to have consistent behavior across runtimes when stripping tags is to do the conversion on the server-side. That's especially needed if you wan to have consistent whitespace treatment in multiline text, since there differences in how browsers treat whitespace. The question how to best strip tags from strings in JavaScript has been answered before on Stackoverflow, e.g. JavaScript: How to strip HTML tags from string?
Here is a cross-runtime example which works in DHTML with Firefox, Chrome, and it should work with IE9+:
<canvas>
<text name="sample" id="gRead" />
<handler name="oninit"><![CDATA[
gRead.setAttribute("text", 'Hello <b>World</b> OL');
Debug.info("gRead.text=" + gRead.text);
if ($dhtml) {
Debug.info(gRead.getDisplayObject().textContent);
} else {
Debug.info(gRead.getDisplayObject().textfield.text);
}
]]></handler>
</canvas>
I found what is the problem. The problem is that i have to declare a variable and have to refer the property from that.
<canvas>
<library>
<text name="sample" id="gRead">
<method name="getTextFrom">
Debug.write("this.text" , this.sprite);
var mx = this.sprite;
Debug.write("this.text" , mx.textfield.text);
</method>
</text>
</library>
<handler name="oninit">
gRead.setAttribute('text',"HI");
gRead.getTextFrom();
</handler>
</canvas>
After following the struts 2 web pages and numerous examples, my application still will not pick up values from the struts.properties file.
I am trying this in order to give some values a money type format:
<s:property value="getText('struts.money.format',{value})" />
My struts.properties file which is under WEB-INF/classes and therefore visible has the following single line
struts.money.format= {0,number,\u00A4##0.00}
I get the string struts.money.format printed to the screen. If I change the first parameter of the getText call, the new string I put also will get printed instead of a true lookup happening.
If I do <s:property value="value" /> I will get back a proper number. If I drop the second argument on the getText call, I would expect to get back the right hand side of the assignment in the properties file, but i get the same struts.money.format back.
I am using Tomcat 6 with Struts 2.2.1.1. Is there an additional part of the puzzle I am possibly leaving out?
So in my struts.xml file, I put this line
<constant name="struts.custom.i18n.resources" value="struts" />
It needs this to know that I am trying to use a struts.properties file. I had assumed that by default a file named struts.properties was along the chain of places to look for a constant such as this. Only if you named it something else did you need to specify that. Even though it is in WEB-INF/classes which is recommended by the Struts 2 documentation, it just simply was not looking in this file.
EDIT
For what it is worth, I also had to modify my struts text tag like so
<s:property value="getText('struts.money.format',{#java.lang.Double#valueOf(value)})" />
Actually, value should have been a BigDecimal, but it was being treated at the view level here as java.lang.String. The problem is that some of the String objects had exponential formatting (like 1.642E07 or something to that effect) and the struts formatter could not handle the exponential formatting. The valueOf eliminates this exponential fomatting
I've been looking for a solution to this problem for some time.
I'm using CF9's cfpdf to populate pdf fields.
One field is a "title" field and one particular title must be
followed by a registered trade mark symbol.
The registered trade mark symbol must be superscript.
Does anyone have any possible solutions?
Thanks so much for your time.
Code snippet:
<cfpdfform
action="populate"
source="#var.workFiles##var.ID#.pdf"
destination="#var.workFiles##var.ID#.pdf" overwrite = "true">
<!--this is the value that could contain the registered trademark -->
<cfpdfformparam name="title" value="#trim(var.title)#">
There might be a shortcut, but try something like this:
<cfset symbol = charsetEncode(binaryDecode("c2ae", "hex"), "utf-8")>
...
<cfpdfformparam name="title" value="XYZ Corporation#symbol#">
To expand on Leigh's answers, I was also having issues with character encoding, specifically the £ sign. which was being shown as A£.
I resolved the issue the same way, by looking for the hexicecimal representation of the £ symbol at http://www.utf8-chartable.de/ (c2a3 for the £ sign) and using the charsetEncode(binaryDecode("c2a3", "hex"), "utf-8") part from Leigh's answer with the correct hex code.
I am using Apache Tiles 2.1 as my templating framework (along with Spring MVC).
I want to know how best to be able to set HTML attribute values from within my Tiles definitions file. For example I have a text box and want to be able to set the maxlength attribute from within my definition. I expected the following to work -
<input id="nameField" type="text"
maxlength="<tiles:insertAttribute name='maxlength' />" />
using this definition -
<definition name="sprint-goal" >
<put-attribute name="maxlength" value="100" />
</definition>
But it seems that Tiles ignores the <insertAttribute/> tag if placed within a HTML tag. It works fine otherwise.
Note: I have tried using a ViewPreparer to set request-scoped values. This will work but is not exactly what I am looking for. I would like to easily set HTML attribute values from within a Tiles definition.
To set the value of html element attributes, your best bet is to use Expression Language. First, expose the tile attribute as a java variable using the tiles useAttribute tag. Then use '${}' to print the variable.
Example:
<tiles:useAttribute name="myMaxLength" id="maxLength" />
<input id="nameField" type="text" maxlength="${myMaxLength}" />
