Re: [S2 V2.0.14] value attribute has rtexprvalue=false - shouldn't it be rtexprvalue=true? - [SOLVED]

Yes, thanks, this works. I was hoping that the IteratorStatus is still available also after </s:iterator>, but apparently this is not so.

Hi Robert,

Best greetings,

This does not sound like what i'm after. I need something like this:

<s:iterator>
-- write iterator row details
</s:iterator>
<s:if test="true if the iterator above did not deliver any rows>
-- message that iterator did not deliver rows goes here
</s:if>

In your iterator, the status attribute defined (e.g., status="stat" in
your case) is an object of type "IteratorStatus".  It has methods
defined: getCount, getIndex, isEven, isFirst, isLast, isOdd, and
modulus.  You could check isLast to find the last row (e.g., stat.isLast
== true).

Thanks Dave, that was a very enlightening suggestion, i'm using
<s:iterator> right now. One thing remains: After </s:iterator>, i need
to know if the iterator that was processed previously delivered rows or
not. How would i accomplish this?

As a workaround, i must use the page context, like so here:


It's not a work-around, that's just how JSP works--you're making more


work than necessary by mixing paradigms: either use all scriptlets and
do things the old way, or use the currently-available constructs and
clean it up.


It'd also be easier to understand (visually) if there was a simpler


way to get the item in the list you're using for the param and link:
iterating over the list would be less cumbersome if you weren't using
the getEntry(row, 0) thing and instead using OGNL to access the list
item's value:


<s:iterate value="#attr.plugh" id="entry" status="stat">
 <tr class="...">
   <td></td>
   <td class="...">
     <s:url id="entryUrl" action="delete">
       <s:param name="mEntry" value="#entry[0]"/>
     </s:url>

     <a href="<s:property value="#entryUrl"/>">
       <s:property value="#entry[0]"/>
     </a>
   </a>
   </td>
 </tr>
</s:iterate>

With clever CSS classnames you can also reduce the <tr...> to


something like:


<tr class="cell<s:property value="#stat.even"/>"> or whatever.
