Title: Nachricht

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"
varStatus="forEachStatus"
items="#dynamicTable.rowLayout.spalten}" >

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

<c:forEach var="forEachColumn"
      varStatus="forEachStatus"
         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:

<tr:table value="#{dynamicTable.data}"
            var="tableRow"
      varStatus="tableStatus"
     rowBandingInterval="1"
           rows="5"
         noWrap="true"
       sortable="true">
<c:forEach var="forEachColumn"
      varStatus="forEachStatus"
         items="#dynamicTable.rowLayout.spalten}" >
    <tr:column   sortable="true"
                   noWrap="true"
             sortProperty="kategorie"
         defaultSortOrder="ascending">
      <f:facet name="header">
         #{forEachColumn.ueberschrift.header} <br />
      </f:facet>
      #{tableRow[forEachColumn.spalte]}
    </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         1.2.1-SNAPSHOT
trinidad                1.2.2
facelets                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.
