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: Jörg Viola
            Priority: Minor


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.
