[jboss-user] [JBoss Seam] - h:dataTable, HashMap, and List

If I've defined a List within a HashMap (which I want to use in h:dataTable component) See below: | private Map <String , List<ScsMessageBlock> > scsMessageBlocks; | Is it possible to reference the List in h:dataTable component? Then would this work ? | <h:dataTable value="#{scsMessageBlocks['SomeKey']}" var="msg" | styleClass="width100" > | | .. | </h:dataTable> | The above code generates the following error even though that key does exist in the HashMap and a List with rows has been allocated. java.lang.IllegalArgumentException: row is unavailable View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4110580#...
