conditional matching using s:if
Hi Struts2 users,
I am new to Struts2
Have a problem with s:if tag, below is the code snippet
'branchsData' is a javaobject having 'branch' as its property
Trying to generate table structure based on condition, i am afraid s:if
conditional tag is not working for me. Let me know what is the problem with
this code and what best way to achieve this
Any help will be greatly appreciated
Thanks in advance
----------------------------- START -------------------------------------
<s:iterator value="branchsData" status="stat">
<s:if test="%{#branchsData[%{#stat.index}].branch =='START'}">
<table><tr>
</s:if>
<s:elseif test="%{#branchsData[%{#stat.index}].branch =='END'}">
</table></tr>
</s:elseif>
<s:else>
<td><s:textfield name="%{#branchsData[%{#stat.index}].branch"
value=""></s:textfield></td>
</s:else>
</s:iterator>

Look into the open source project called displayTag, I think that will
save a lot of headaches and reinventing the wheel.

Hello DharmaRao,
take a look at the s:iterator and s:subset Tag.
They allow you to iterate over a list for example and also take subsets
out of it.

deko babu,
Cognizant people are supposed to be the experts
therefore they should not ask for help like this.
Unfortunately, I am also looking for the same answer

help - pagination using struts2
Posted by Dh...@cognizant.com.
HI
I am not able to find out pagination using Struts2.
Is there any tag lib ( which is similar to struts layout in Struts 1.x)
available in Struts2.
Could any one guide me or send me some sample code.
thanks and regards
DharmaRao

Thanks for the help
Could get what i wanted by using the s:set tag. Code snippet below
----------------------
<s:iterator value="allBranches" status="stat">
<div style="display:none"><s:set name="brname"><s:property/></s:set></div>
<s:if test="%{#brname=='START'}">
<table class="gridTable" id='<s:property/>'><tr>
</s:if>
<s:elseif test="%{#brname=='END'}">
</table></tr>
</s:elseif>
<s:else>
<th width="65"><s:property/></th>
<td><s:textfield id="" name="%{#brname}" size="4"
value=""></s:textfield></td>
</s:else>
</s:iterator>

Without seeing more of your code I can't be sure, but (see inline):

if that's the case, why are you trying to iterate it with s:iterator?
I'll assume below that branchsData is actually some sort of collection
(array or list) of objects where each object has a 'branch' property.

It looks like you may be trying to encode presentational information in
your data. Those OGNL expressions look suspicious to me, too; why are
you trying to do the indexing manually, instead of letting s:iterator
handle it for you?
The simple solution is to get rid of the conditional rendering stuff
like so:
<table><tr>
<s:iterator var="branch" value="branchsData" stat="stat">
<td><s:textfield name="branch"/></td>
</s:iterator>
</tr></table>
If branch=='START' and branch='END' are just placeholder/delimiter
entries to separate logical groups of entries, consider making your data
structure a list of lists of branches, where the intermediate list does
the grouping.
If that doesn't help, try posting a more complete description of what
you're trying to achieve. Maybe there are more suitable changes that can
be applied to your data structure and/or presentation logic to get there.
