Unable to navigate into a PersistentSet (always displays Set

[infinity2heaven]

I have a rich:dataTable

<rich:dataTable value="#{questionController.questions}"
 var="question" rows="20" rowKeyVar="row" ...>
 <!-- somewhere below -->
 <rich:column>
 <rich:dataList var="category" value="#{question.categories}">
 <h:outputText value="#{category.}
 </rich:dataList>
 </rich:column>
</rich:dataTable>

I'm getting a 'PeristentSet' at the line #{Category}, rather than category object. This is bizarre since debugging on the server side (questionController.gquestions) clearly shows a complete graph of obects
question->HashSet of Categories.

What am I missing?

Try to remove dot after category.

<h:outputText value="#{category.} <-- Look here

and add closing tag ;)

Hi,

Sets are not supported: https://jira.jboss.org/jira/browse/RF-2811. You can use workaround described in the issue.

Thanks. Works.

Although, it seems ridiculous that richfaces doesn't want to fix this.
