It needs some state - a stateless bean looses state between each invocation - it is invoked update data model (i think?) to set the datamodel selection, and then in INVOKE_APPLICATION to call the action - the state is lost between these.  Further, you need to hold the state of the datamodel between the two requests - this is due to how JSF works (the restore view phase).  The PAGE or CONVERSATION scope is ideal for this

[qupte]Don't ever set var="org" in a dataTable.  Doing so causes Seam to go nuts searching contexts and it eventually throws an exception because can't find a property called 'jboss' in the entity bean.  Should I report this as a bug?  I'd be happy to provide a test case.  Using var="o" changes the behavior completely.
