jx:forEach returns JXTExpression where com.xxxx.Group is Expected

["Robby Pelssers, AGP" <ro...@agp.nl>]

<jx:set var="subGroupIterator"
value="${planboard.analyzer.rootGroup.subGroupIterator(planboard.projectGrou
pRule)}"/> 

<jx:forEach var="projectGroup" items="{subGroupIterator}">

  <jx:set value="${java.lang.System.err.println(projectGroup)}"/>

</jx:forEach>

 

A print of SubGroupIterator results in java.util.AbstractList$Itr@35135a

A print of projectGroup results in
org.apache.cocoon.generation.JXTemplateGenerator$JXTExpression@
<mailto:org.apache.cocoon.generation.JXTemplateGenerator$JXTExpression@89a2d
9> 89a2d9

 
Anybody who has an explanation??  And solution for my problem :-)  
 
PS.  Even when I don't use the <jx:set var = .../>  construction, but
directly  
 
<jx:forEach var="projectGroup"
items="{planboard.analyzer.rootGroup.subGroupIterator(planboard.projectGroup
Rule)}">
</jx:forEach>
 
the problem remains the same.
 
 
 
Cheers,

Robby Pelssers

Not sure what's happening, but I have a couple questions:

1) Which version of JXTemplateGenerator are you using?  The main one in 
the core distribution or the new-jx version from the 'template' block?

2) I assume it's a typo, but are you omitting the '$' from the start of 
your items="" expression?
