Nothing helps
attribute "var" doesn't exist in my struts-tags.tld. I'm using the last one
struts2 pack.
lawDraft.docs returns List with 5 elements.
Simple printing </s:property value="lawDraft.docs"> shows 5 elements
I've tried to invoke method "getTitle()" of class Document which instances
are in ArrayList:
1.
<s:iterator value="lawDraft.docs" status="document" id="doc">
</s:property value ="title">
</s:iterator>
Nothing, empty string
2.
<s:iterator value="lawDraft.docs" status="document" id="doc">
</s:property value ="%{#doc.title}">
</s:iterator>
Nothing, empty string
Previous actions prints to log fields of objects kept in Lawdraft.getDocs()
I know, that title is not null or empty.
Can you suggest me something else?

"var" attribute is used as from S2.1 and above which was not released
yet (2.1.2 is beta), the latest release is 2.0.11.2, which version do
you have?

Re: Iterator index: how to index html elements?

Hi,

For this I usually do something like (untested):
<s:iterator ...>
<s:set var="i" value="%{#status.index}"/>
<tr id="row_${i}">...</tr>
</s:iterator>
Btw, you can't use OGNL expression in non-struts tags (you tried to use
it in tr).
There's a tabletags taglib for struts2, which might be useful for you.
Hope that helps,
Joachim

None that I'm aware of; I use it all the time.
I'd strongly recommend not naming your status variable "document", since it's not a document. It's a status.
It wouldn't be #document.status, it would be #document.index; see [1].

Re: Iterator index: how to index html elements? count works, but status doesn't
Posted by Jim Kiley <jh...@summa-tech.com>.
The version of IteratorStatus found in version 2.0.11 of the docs [1] has a
getIndex() method; has it subsequently been vaporized?

Re: Iterator index: how to index html elements?
Posted by holod <se...@gmail.com>.
That's not valid JSP; you can't nest tags like that.
> Any suggestions, please, can't understand mistake.
That's not what <s:param...> is for; it's for parameterizing other tags.
<tr id="foo<s:property value="#status.index">">bar</tr>
You could use <s:set...> to create the ID if you don't want to create it
on-the-fly.
<tr id="attachedMainDocRow<s:property value="#document.status"/>">
Some content
</tr>
When I inspect source of generated html page, I see:
<tr id="attachedMainDocRow">
Some content
</tr>
My rows were printed several times (that's ok), but #document.status is not
used, seems like it's "" or null, but it can't be so. My iterator iterates
several times and gets values from list.
Is there any issues with status of iterator?

Iterator index: how to index html elements?
Posted by holod <se...@gmail.com>.
Now, I have another problem:
My iterator generates <tr>some content</tr>
I want to give id="bla-bla" to my generated raws of table.
For example iterator makes 5 iterations, I get 5 rows (<tr>some
content</tr>), but I want to set id attribute for them:
<tr id="MyGeneratedRow0">some content</tr>
<tr id="MyGeneratedRow1">some content</tr>
<tr id="MyGeneratedRow2">some content</tr>
<tr id="MyGeneratedRow3">some content</tr>
<tr id="MyGeneratedRow4">some content</tr>
I use this code:
<s:iterator value="lawDraft.docs" id="doc" status="document">
<s:param name="rawMainDocIdParam" value="attachedMainDocRow<s:property
value="document.index"/>"/>
<tr id="%{#rawMainDocIdParam}">
some content
</tr>
</s:iterator>
The problem is: I'm trying to access status (starts from 0) of iterator,
I've tried
<s:param name="rawMainDocIdParam" value="attachedMainDocRow<s:property
value="document.index"/>"/>
I get error: "No information about attribute tag document.index"
I've tried
<s:param name="rawMainDocIdParam" value="attachedMainDocRow<s:property
value="#document.index"/>"/>
and
<s:param name="rawMainDocIdParam" value="attachedMainDocRow<s:property
value="%{#document.index}"/>"/>
In both cases I get error "Can't convert to xml document.index"
Any suggestions, please, can't understand mistake.

Just as a side note, message subject lines like "Nothing helps" and "A
similar problem" should probably be avoided on this list. When someone
looks at the archives because they're stumped about a problem with
displaying problems within an iterator, there's no signal that this thread,
for instance, might give them information about their problem.

Thank you, I've finally solved the problem! Previous solutions helped me,
seems like I was making stupid mistakes.
This code snippet prints links to my download action, my download action
works fine.
Thank you again!

RE: Nothing helps
Posted by Jishnu Viswanath <ji...@tavant.com>.
1.If var does not exist u are using struts 2.0.x not 2.1.x
2. Try doing something like this so this
<s:iterator value="lawDraft.docs>
<div>one</div>
</s:iterator>
If one prints atleast one time then you have lawDraft.docs exists as a
List
3.
Say u have a classes
Class LawDraftAction{
LawDraft lawDraft;
//Getter setters
}
Class LawDraft{
List<Document> docs;
//Getter Setter
}
Class Document{
String title;
//Getter Setter again :P
}
Then in jsp you can write
<s:iterator value="lawDraft.docs>
Document Title: <s:property value="title"/>
</s:iterator>
