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?
