Paul,
Did you tried trunk?
The source of this problem was not in the EvalNode class itself (that is
why you mention the code is still there), but on the re-use of node ids,
that determine the position of the node memory in the memory array. I fixed
this in trunk a few weeks ago. Give it a try and let me know if you still
see any problem, but I think it is everything fine now.
https://jira.jboss.org/browse/JBRULES-2312
Thanks,
Edson
