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}" />

<put-attribute name="maxlength" value="100" type="string" />
I type isn't defined as "string" it would be taken as a URL to include...

The framework I am using is .NET 6.
Previously, the src attribute of the image element like this:
<img src="#ImageServer/images/BG.png" />
The variable of ImageServer stores the URL of the image server.
Recently, I need to add a token in it for anti-theft chain.
I tried it like this:
<img src="#ImageServer/images/BG.png#GetToken()" />
However, after the program is run, the src turns out to be this:
<img src="https://www.aaa.com/images/BG.png#GetToken()" />
What's wrong with my code and how can I render two variables in src attribute? Thank you.
The text just before the # is causing the render engine to not parse the # as a server-side code indicator.
Make the whole value server-side calculated, instead of outputting small pieces of server-side values into client-side values. For example:
<img src="#(ImageServer + "/images/BG.png" + GetToken())" />
This way the view engine sees everything within the #() as a server-side expression and outputs the result of that expression.
Similarly, with string interpolation:
<img src="#($"{ImageServer}/images/BG.png{GetToken()}")" />
My First Question, after years, thank you all and stackoverflow ;-)
I code a new Component for JSF2 and use it to include other templates.
It works perfectly for me.
<cc:interface>
<cc:attribute name="src" type="java.lang.String" required="true"/>
<cc:attribute name="addOption" type="java.util.List"/>
</cc:interface>
<cc:implementation>
<cc:insertChildren />
<ui:include src="#{BeanAnything.convert(cc.attrs.src, cc.attrs.addOption)}" />
</cc:implementation>
But i cant complete the Parameter src via auto completion in intellij or netbeans with "strg + space" or whatever other will use.
It should be used like the ui:include on src parameter.
Any Ideas ?
That's what I want to achieve only with my own componente gg:include
See Example
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>
A set of forms (using Zend_Form) that I have been working on were causing me some headaches trying to figure out what was wrong with my XML configuration, as I kept getting unexpected HTML output for a particular INPUT element. It was supposed to be getting a default value, but nothing appeared.
It appears that the following 2 pieces of XML are not equal when used to instantiate Zend_Form:
Snippet #1:
<form>
<elements>
<test type="hidden">
<options ignore="true" value="foo"/>
</test>
</elements>
</form>
Snippet #2:
<form>
<elements>
<test type="hidden">
<options ignore="true">
<value>foo</value>
</options>
</test>
</elements>
</form>
The type of the element doesn't appear to make a difference, so it doesn't appear to be related to hidden fields.
Is this expected or not?
As it was rather quiet on here, I took a look further into the source code and documentation.
On line 259 of Zend_Config_Xml, the SimpleXMLElement object attributes are converted to a string, resulting in:
options Object of: SimpleXMLElement
#attributes Array [2]
label (string:7) I can't see this because
value (string:21) something happens to this
becoming
options (string:21) something happens to this
So, I hunted through the documentation only to find that "value" is a reserved keyword when used as an attribute in an XML file that is loaded into Zend_Config_Xml:
Example #2 Using Tag Attributes in Zend_Config_Xml
"..Zend_Config_Xml also supports two
additional ways of defining nodes in
the configuration. Both make use of
attributes. Since the extends and the
value attributes are reserved keywords
(the latter one by the second way of
using attributes), they may not be
used..."
Thus, it would appear to be "expected" according to the documentation.
I'm not entirely happy that this is a good idea though, considering "value" is an attribute of form elements.
Don't worry about this. The reserved keywords were moved to their own namespace, and the previous attributes were depricated. In Zend Framework 2.0 the non-namespaced attributes will be removed so you can use them again.
I am adding a new field to a list using the AddFieldAsXML method of SPFieldCollection. The method executes fine with no problem. And the column header shows up when I view the list; however the value never displays in the column. Here is what the field looks like after it has been added to the list. This xml is a snipped from the list schema derived using http://tw-s1-m4400-007:4016/_vti_bin/owssvr.dll?Cmd=ExportList&List={1F87433F-50E1-46C5-A138-00E1CF7E5801}
This code works great in 2007 but does not work in 2010. Any help would be appreciated.

This link provided a lot of help in solving this issue:

Basically, display patterns fields are defined in the C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\XSL\fldtypes.xsl file.
There is a file called fldtypes_ratings.xsl that you can use as an example of defining your custom field display.
You can create your own xsl file (i.e. fldtypes_myfile.xsl) to define your own custom display.
Here's a sample of my content:
<xsl:stylesheet xmlns:x="http://www.w3.org/2001/XMLSchema"
xmlns:d="http://schemas.microsoft.com/sharepoint/dsp" version="1.0" exclude-result-

Hope that helps!
I'm confused as to the point of referencing these articles -- both of them state "Two legacy field types that ship with SharePoint Foundation do not have a DisplayPattern type of RenderPattern in FLDTYPES.XML: (1) ContentTypeId fields are never visible. (2) Computed fields are rendered on list views and in Display mode by a DisplayPattern element in their Field elements within the schema.xml of each list on which they appear."
The original question is clearly defined as a "Computed" field, that according to the linked articles do not use the fldttypes.xml for their renderpattern, but intstead use the DisplayPattern element just as the original question posted. It would help to post references to how the DisplayPattern works in 2010 -- since the documentation clearly states that it Does work, but never says how.
See my blog on this here: http://www.threewill.com/2012/07/computed-fields-in-sp-2010/. Hopefully this makes it clear on how to do computed fields in SP2010.
This method of customization from 2007 is made obselete by changes in 2010's rendering of fields. Read the note from the SDK entry on RenderPattern for more detail:
Important!
This topic describes markup that was used in a now obsolete method of rendering custom fields types on list views and on the Display, Edit, and New forms. It is provided solely to assist persons who are debugging a custom field type that was originally developed against an earlier version of SharePoint Foundation. For information about the recommended methods, see How to: Create Field Rendering Templates and How to: Create a Custom Field Type.
Custom fields whose rendering is defined with RenderPattern markup still render properly on forms. However, SharePoint Foundation, by default, uses XSLT stylesheets to render fields on list views, even for legacy custom fields whose list view rendering is defined with a RenderPattern. To enable the rendering of such a field, a TRUE element must be added to the containing FieldTypes element in the field type definition file (fldtype*.xml).
