[jboss-jira] [JBoss JIRA] Resolved: (JBRULES-2584) java.lang.UnsupportedOperationException: LeftTupleSinkUpdateAdapter onlys supports assertLeftTuple method calls

Edson Tirelli resolved JBRULES-2584.
------------------------------------

    Resolution: Done


Eval nodes use a LeftTupleSinkAdapter when dynamically adding nodes to the network and as so, the eval source nodes were incorrectly creating tuples pointing to the adapter instead of the node itself.

Fixed.
