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

In _createElement, I want to ask whether data.is is same to the v-bind:is?
https://github.com/vuejs/vue/blob/0baa129d4cad44cf1847b0eaf07e95d4c71ab494/src/core/vdom/create-element.js#L64
Why tag = data.is?
Thanks for every respondent!
As the comment in the code suggests, that line is specifically to handle the case where is is included inside an object v-bind. e.g.:
<component v-bind="{ is: 'button' }">Button</component>
You can see this for yourself by setting a breakpoint in your browser on that line. I'm using Webpack and Chrome and the relevant file appears under webpack:///./node_modules/vue/dist/vue.esm.js in the Sources tab. Quick search for _createElement and click in the margin to set a breakpoint.
In the example above the is value is intended to be used as the tag, whereas component is just a dummy tag that can be discarded.
The syntax above is equivalent to:
<component is="button">Button</component>
or:
<button>Button</button>
However, neither of these two examples will go into the relevant if section. In these other two cases the tag is already resolved correctly prior to this point.
So in my targets file, I've got a line that looks like this:
<XmlPeek Namespaces="" XmlInputPath="file.xml" Query="/data/#AttributeOne">
<Output TaskParameter="Result" ItemName="my_AttributeOne" />
</XmlPeek>
in "file.xml", I have:
<data AttributeOne="abc" AttributeTwo="def" />
it also reads a few other attributes.
When the attribute has data, everything works fine... but when I leave AttributeOne as an empty string (""), XmlPeek blows chunks with the following error:
The "XmlPeek" task's outputs could not be retrieved from the "Result" parameter. Parameter "includeEscaped" cannot have zero length.
if I remove the attribute ENTIRELY, it works fine (the resulting item is obviously and understandably blank)
The question is... how can I DETERMINE, WITHOUT blowing chunks, the value of a blank attribute... whether by pre-testing for a value, or by correctly handling the blank, or some other means.
CONSTRAINT: the only real requirement is to stick to the built-in tasks (XmlPeek)... I'm aware of XmlRead in the community tasks... for various reasons, I want to use out-of-the-box tasks.
Thanks in advance!
The error happens because an empty string is being used as the Item Identifier. I guess identifiers cannot be the empty string. If you remove the attribute then the result is null and no Item is created so that's why that doesn't throw an error.
Maybe try return the result as a Property instead of an Item.
If you do not need to distinguish between the attribute being omitted versus having an empty value, you can prevent the error by inserting the condition [#AttributeOne!=''] into the query as follows.
<XmlPeek Namespaces="" XmlInputPath="file.xml" Query="/data[#AttributeOne!='']/#AttributeOne">
<Output TaskParameter="Result" ItemName="my_AttributeOne" />
</XmlPeek>
I am trying to set a flag so I do something like this:
<set field="existingFound" value="false" type="Boolean"/>
but the following line prints "true" in the log:
<log message="storeProperty, existingFound (0): ${existingFound}"/>
What is the best way to set flags?
The set.#value attribute is interpreted as a Groovy String (GString) so any non-empty value will be interpreted as true. The set.#from attribute is interpreted as a Groovy expression, so simply using from="false" instead of value="false" will get the desired result.
To see the generated Groovy code from an XML actions block you can write code that will cause an error and then the script will be logged, or you can change the log4j.xml file to turn on "debug" level logging for the XmlActions class (the latest log4j.xml file in the GitHub repository has an example of this). Looking at the Groovy code generated from the XML elements is a good way to track down issues when what is happening just doesn't make sense.
When running a report in preview I get the following error The definition of the report is invalid , the tablix 'Tablix11' contains an invalid TablixMember. The sort Expressions element is not allowed if Group is omitted.
I have never come across this error before and cant understand what is causing it.
The error can be replicated by creating a simple Tablix and looking at the underlying XML.
When you create a Tablix with a group, the underlying RDL XML will include something like this:
<TablixRowHierarchy>
<TablixMembers>
<TablixMember />
<TablixMember>
<Group Name="Group1">
<GroupExpressions>
<GroupExpression>=Fields!val.Value</GroupExpression>
</GroupExpressions>
</Group>
<SortExpressions>
<SortExpression>
<Value>=Fields!val.Value</Value>
</SortExpression>
</SortExpressions>
<TablixMembers>
<TablixMember>
<Group Name="Details3" />
</TablixMember>
</TablixMembers>
</TablixMember>
</TablixMembers>
</TablixRowHierarchy>
If you remove the entire Group element, this will give the same error you're seeing:
If you also remove the SortExpressions element this will allow the report to render without error.
However - it's impossible for me to say how your RDL file got in this state in the first place. Given that hacking XML to get things running is seldom a good idea, my recommendation would be to start the tablix from scratch instead of hacking things to a working state - you might just be introducing more problems.
But at least hopefully now you can see why the error might be occurring.
I found that the Tablix header had a textbox property containing interactive sort. This text box is in the header, and not part of the detail. When I deleted the field from the detail of the tablix, the interactive sort remained on the textbox in the header.
Changing it on the header by right clicking on the header textbox of the tablix, then selecting textbox properties, then selecting "interactive sorting", and then correcting the "sort by" value to the correct field name did the trick.
I'm looking for a way to receive a XML Element (the id of an entry) from a YouTube feed (e.g. http://gdata.youtube.com/feeds/api/users/USERNAME/uploads).
The feed looks like this:
<feed xmlns="http://www.w3.org/2005/Atom" xmlns:media="http://search.yahoo.com/mrss/" xmlns:openSearch="http://a9.com/-/spec/opensearch/1.1/" xmlns:gd="http://schemas.google.com/g/2005" xmlns:yt="http://gdata.youtube.com/schemas/2007" gd:etag="W/"DUcFQncyfCp7I2A9WhVUFE4."">
<id>tag:youtube.com,2008:user:USERNAME:uploads</id>
<updated>2012-05-19T14:16:53.994Z</updated>
...
<entry gd:etag="W/"DE8NSX47eCp7I2A9WhVUFE4."">
<id>tag:youtube.com,2008:video:MfPpj7f6Jj0</id>
<published>2012-05-18T13:30:38.000Z</published>
...
I want to get the first tag in entry (tag:youtube.com, 2008 ...).
After googling for some hours and looking through the GDataXML wiki, I'm clueless because neither XPath nor GData could deliver the right element.
My first guess is, they can't ignore the attributes in the feed and entry tags.
A solution using XPath would be great, but one in Objective-C is equally welcome.
You might be having an issue trying to get XPath to work because of the default namespace.
If you just want the first tag in entry, you can use this:
/*/*[name()='entry']/*[1]
If you want the first id specifically, you can use this:
/*/*[name()='entry']/*[name()='id'][1]
Also if you can use XPath 2.0, you can skip the predicate entirely and use * for the namespace prefix:
/*/*:entry/*:id[1]
