If the code you are using is as you show it in the message, then appear to have a syntax error in:

 <c:forEach var="forEachColumn"
 &nbsp; &nbsp;  varStatus="forEachStatus"
 &nbsp; &nbsp; &nbsp; &nbsp; items="#dynamicTable.rowLayout.spalten}" >

You appear to be missing a leading brace and it should probably be:

 ;<c:forEach var="forEachColumn"
 &nbsp; &nbsp;  varStatus="forEachStatus"
 &nbsp; &nbsp; &nbsp; &nbsp; items="#{dynamicTable.rowLayout.spalten}" >

Subject: Problem mixing c:forEach and Trinidad tr:table and tr:column

Hi to all,

I' ve some problems while trying to build a table dynamically.
We have some meta-objects (named RowLayout) that describe,

• which columns will be displayed
• which heading is used
• is the column sortable and what is the name of the sortProperty.
  

This approach works fine, as far as I use the EL-expressions "forEachColumn" and "forEachStatus" within the body of a tr:column tag.

But, if I try to set the attribute sortProperty with an EL-expression I get a ClassNotFoundException.
As far as I could see, the mentioned class is present in facelets.jar.

Here is the code snippet from my Facelet:
<!-- OK
 &nbsp; &nbsp; &nbsp; &nbsp;   ; <tr:column &nbsp; sortable="true"
 &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp; &nbsp; &nbsp;  sortProperty="kategorie">

 &nbsp;  NOT OK:
 &nbsp; &nbsp; &nbsp; &nbsp;   ; <tr:column &nbsp; sortable="true"
 &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp; &nbsp; &nbsp;   sortProperty="#{forEachColumn.spalte}">

java.lang.ClassNotFoundException: com.sun.facelets.tag.jstl.core.IndexedValueExpression
org.apache.myfaces.trinidadinternal.application.StateManagerImpl restoreView
SEVERE: No structure available and no root available
org.apache.myfaces.trinidadinternal.config.xmlHttp.XmlHttpConfigurator handleError
SEVERE: Server Exception during PPR, #19

-->
<tr:table value="#{dynamicTable.data}"
 &nbsp; &nbsp; &nbsp; &nbsp;   ; var="tableRow"
 &nbsp; &nbsp;  varStatus="tableStatus"
 &nbsp; &nbsp; rowBandingInterval="1"
  &nbsp; &nbsp; &nbsp; &nbsp;  rows="5"
 &nbsp; &nbsp; &nbsp; &nbsp; noWrap="true"
 &nbsp; &nbsp; &nbsp; sortable="true">
 <c:forEach var="forEachColumn"
 &nbsp; &nbsp;  varStatus="forEachStatus"
 &nbsp; &nbsp; &nbsp; &nbsp; items="#dynamicTable.rowLayout.spalten}" >
 &nbsp;  <tr:column&nbsp;  sortable="true"
 &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp; &nbsp;  noWrap="true"
 &nbsp; &nbsp; &nbsp; &nbsp;   ;  sortProperty="kategorie"
 &nbsp; &nbsp; &nbsp; &nbsp; defaultSortOrder="ascending">
 &nbsp; &nbsp;  <f:facet name="header">
 &nbsp; &nbsp; &nbsp; &nbsp; #{forEachColumn.ueberschrift.header} <br />
 &nbsp; &nbsp;  </f:facet>
 &nbsp; &nbsp;  #{tableRow[forEachColumn.spalte]}
 &nbsp;  </tr:column>
  </c:forEach>
</tr:table>

Everything works fine, if sortProperty is a literal (and no EL-expression).
With an EL-expression instead, I get an ClassNotFoundException followed by a NullPointerException.

Our environment is:
myFaces  &nbsp; &nbsp; &nbsp;  1.2.1-SNAPSHOT
trinidad  &nbsp; &nbsp; &nbsp;  &nbsp; &nbsp; &nbsp;  1.2.2
facelets&nbsp; &nbsp;   ;   &nbsp; &nbsp; &nbsp;  1.1.13

My question now is:
Why can I use EL-expression within the body of tr:column, but not to set an attribute of tr:column?

Thanks for your help.
