rich:columns causes NotSerializableException -------------------------------------------- Key: RF-4510 URL: https://jira.jboss.org/jira/browse/RF-4510 Project: RichFaces Issue Type: Bug Affects Versions: 3.2.2 Environment: JBoss AS 4.2.2.GA, Seam 2.0.2.SP1 Reporter: Joerg Viola Assignee: Andrei Markavtsov Priority: Minor Fix For: 3.3.0 We are deploying to a clustered environment (server/all). and thus rely on the http session to be serializable. After entering a page using the follwing code <rich:dataTable value="#{customerOverviewStatus.rows}" var="row"> <rich:columns value="#{customerOverviewStatus.productFamilies}" var="productFamily" index="idx" styleClass="#{row[idx].backgroundStyleClass}" style="text-align:center;"> <f:facet name="header"> <h:outputText rendered="#{not empty productFamily}" value="#{productFamily.name}" /> </f:facet> <ui:repeat value="#{row[idx].icons.toArray()}" var="icon"> <h:graphicImage value="/img/#{icon.src}" alt="#{icon.alt}" /> </ui:repeat> <h:outputText rendered="#{not empty row[idx].text}" value="#{row[idx].text} " /> </rich:columns> </rich:dataTable> we get this exception: java.io.NotSerializableException: org.richfaces.taglib.IteratedExpression at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1075) ..... The IteratedExpression object causing the Exception says it is working on "#{customerOverviewStatus.productFamilies}". After re-writing the code without rich:columns, everything is working.
