Last time thru iterate? [message #16046]

We're trying to create a template which generates a JSP that conforms to our
JSP syntax (tags etc..). We're iterating over the fields we want in a table
and outputing the approriate tags for our table tag. But we want the last
time through to add one additonal piece of output. (ie:
class="lastChild"). Does anyone know a way to do this with the iterate tag
(short of putting "last='true'" in my meta-data)???

Thanks!
Gary

Gary:

This would be a great enhancement. I've created bug 187524
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=187524) to track it.

In the meantime,

You could do something like the following. Let's assume this is your current
iterate tag:

<c:iterate select="yourXPathExpr" var="...">
</c:iterate>

The, do the following:

<c:setVariable var="iterateCount" select="count(yourXPathExpr)"/>
<c:setVariable var="iterateIndex" select=" 0 "/>
<c:iterate select="yourXPathExpr" var="...">
<c:setVariable var="iterateIndex" select = "$iterateIndex + 1"/>
... body of your iterate...
<c:if test="$iterateIndex = $iterateCount">
... special content for the last iteration...
</c:if>
</c:iterate>
