Hi to all, is anybody out there, who has an idea on this issue? It is absolutely possible to reference an EL-variable (forEachColumn or forEachStatus), that is defined by c:forEach, within the body or the header facet of tr:column. But as soon as I reference one of these EL-variables within my EL-expression for the Attribute sortProperty the mentioned Exception is thrown. Are there any differences in EL-resolving between tag-attributes and the body of a tag? As I am relatively new to JSF, I want to understand, why one part works and the other won't. For my current project it would be important to get this solution to work. Any help would be appreciated. Kind regards Harald Kuhn

But this is only a typo this message as I am able to reference #{forEachColumn.ueberschrift.header} in the header facet and #{tableRow[forEachColumn.spalte]} in the body of <tr:document>. The Exception appears as soon as I reference the "forEachColumn" within the attribute "sortProperty" like: <tr:column sortable="true" sortProperty="#{forEachColumn.spalte}"> So the question is. What is the difference between EL-Expression in the body (facet) of the <tr:column> Tag and EL-Expression within attribute definition?

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 <tr:column sortable="true" sortProperty="kategorie"> NOT OK: <tr:column sortable="true" 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 java.lang.NullPointerException --> <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?
