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

Subject: [rules-users] Flow Timer causes exception: Caused by:<br>
java.util.concurrent.RejectedExecutionException<br>
<br>
</div><div><div></div><div class="h5">Hi,<br>
<br>
I have a flow and a set of rules.<br>
In the flow I have a wait state. If the wait state has a timer, when<br>
the flow reaches the node it blows up with the following exception (<br>
See Below ), if I remove the timer everything works.<br>
