reference SOA-450
--------------------------------------------------------------------------------------------------------
Key: JBPM-1143
URL: http://jira.jboss.com/jira/browse/JBPM-1143
Project: JBoss jBPM
Issue Type: Bug
Components: Core Engine
Affects Versions: jBPM jPDL 3.2.2
Environment: T60 laptop running RHEL 5, Java 1.5, SOA Platform 4.2 CR3
Reporter: Jeff DeLong
Assigned To: Tom Baeyens
I have defined a process definition with the following decision node where Account is a
POJO. I can see that the Account as a jBPM variable in the jBPM Admin Console.
<decision name="Sufficient Funds in Account?"
expression="#{account.balance > tollTransaction.toll} ">
<transition to="Post Toll Transaction to Account"
name="true"></transition>
<transition to="Replenish Account"
name="false"></transition>
</decision>
When I execute the process, I get the following errors:
15:55:39,123 ERROR [GraphElement] action threw exception: decision 'Sufficient Funds
in Account?' selected non existing transition 'true '
org.jbpm.JbpmException: decision 'Sufficient Funds in Account?' selected non
existing transition 'true '

I then tried the following (simpler) expression, and got a similar result:
#{account.balance > 100}
16:07:28,807 ERROR [GraphElement] action threw exception: decision 'Sufficient Funds
in Account?' selected non existing transition 'false '
org.jbpm.JbpmException: decision 'Sufficient Funds in Account?' selected non
