Hello All,
Why don't we have an community forum website like JBoss Drools forum where
we can post questions/answers unlike this mailing list and if someone has to
go back to old posts, how tough it gets to go thru email archives.
No offence here.
Thanks

Subject: [rules-users] Flow Timer causes exception: Caused by:
java.util.concurrent.RejectedExecutionException
Hi,
I have a flow and a set of rules.
In the flow I have a wait state. If the wait state has a timer, when
the flow reaches the node it blows up with the following exception (
See Below ), if I remove the timer everything works.
