[jbpm-issues] [JBoss JIRA] Created: (JBPM-2834) Conditional transition cannot be considered as a default one
Conditional transition cannot be considered as a default one
------------------------------------------------------------
Key: JBPM-2834
URL: https://jira.jboss.org/jira/browse/JBPM-2834
Project: jBPM
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Runtime Engine
Affects Versions: jBPM 3.2.8, jBPM 3.2.9
Environment: SOA-P 4.3.CP03 ER1
Reporter: Martin Vecera
The documentation reads:
====
The contents of the condition element is a jPDL expression that should evaluate to a
boolean. A decision takes the first transition (as ordered in the processdefinition.xml)
for which the expression resolves to true. If none of the conditions resolve to true, the
default leaving transition (== the first one) will be taken.
====
If I have only a conditional transition in a node (hence the first one) it is not used as
the default leaving transition.
Process definition to simulate the behaviour:
====
<?xml version="1.0" encoding="UTF-8"?>
<process-definition xmlns="urn:jbpm.org:jpdl-3.2"
name="processDefinition3">
<start-state name="start">
<transition to="node1"></transition>
</start-state>
<node name="node1" async="true">
<transition to="node2" condition="#{AAA ==
null}"></transition>
</node>
<node name="node2">
<transition to="end1"></transition>
</node>
<end-state name="end1"></end-state>
</process-definition>
====
