      My page contain rich:dataTable, rich:datascroller. Also i have following rich:column than consist function for text cutting.

      <rich:column>
 <f:facet name="header">
 <h:outputText value="description" />
 </f:facet>
 <h:outputText value="#{mylib:substring(item.description,100)}" />
</rich:column>

      Process rendering page occur without problem when i call my page for the first time. But I have problem when i call next page. My function is mylib:substring from my functions facelets library. Following exception occur when i go to other page :
