Ok, I think we're both getting frustrated :) Perhaps I'm not understanding or explaining things right. 1) Is this right? In my ExpressionHandler, do something like: | assign(Assignable assignable, ExecutionContext executionContext) { | // do some stuff to dynamically figure out what group to assign to | assignable.setPooledActors(new String[] { "group(my-dynamic-group)"}); | } | 2) I would actually like to do task lookups by pooled actorId, not group id. If this is not possible, I can probably get around it. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4223073#...
