> 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.
