> I could not pass a jbpm context variable to a seam component. I'm using seam 2.0.2.SP1, but the same code is still present in trunk. I tracked down the bug to the following method in class org.jboss.seam.bpm.JbpmELResolver
> public Object getValue(ELContext context, Object base, Object property)
> {
> if ( base==null && property!=null )
> {
> return resolver.resolveVariable( (String) base );
> }
> else
> {
> return null;
> }
> }
> note that base is passed into resolveVariable instead of property. I think it should be property. also, the isResolved property of ELContext is not set to true.
> If i manually set these two values in a debugging session, the code worked as expected.
> Proposed fix:
> public Object getValue(ELContext context, Object base, Object property)
> {
> if ( base==null && property!=null )
> {
> context.setPropertyResolved(true);
> return resolver.resolveVariable( (String) property );
> }
> else
> {
> return null;
> }
> }
> A bit more context:
> I had this in my workflow description:
> <task-node name="importanttask">
> <task name="justdoit">
> <assignment pooled-actors="#seamcomponent.getActor(taskInstance)}"/>
> </task>
> <transition to="nextstep" name="donext"/>
> </task-node>
> Without the above fix, the getActor() method on seamcomponent is called with null, with the fix i get passed in the actual task instance.
