Hi,
I'm starting to use Seam and i've got some problems using Drools in order to
manage decisions in my process and nobody is able to help me on Seam forum.
Configuration Jboss 5.0.0 GA Seam 2.1.1 GA Ant 1.7 Jboss Tool Eclipse 3.4
When i use Drools to manage assignment, it works fine, but now i would like to
use it for decison managment and i got this error:
Exception during request processing:
| Caused by javax.el.ELException with message: "org.jbpm.JbpmException:
decision 'decision69' selected non existing transition 'null'"
I give you a part of my code but if something else is needed tell me.
Process:
| <task-node name="PlaceOrder">
| <task name="placeOrderTask">

AccountAproval.drl:
| package AccountApproval;

| import org.jboss.seam.drools.Decision;
|
| global Decision decision
|
| rule "Approve Order For Loyal Customer"
