[jboss-user] [JBoss jBPM] - Re: jpdl-3.2.Beta2: how to access variable from task form in

[avbentem]

...solved!

This may be caused by using a more recent version of the Hibernate libraries (though I doubt the older version would not create an empty List), or maybe is simply a bug that everyone would suffer. I did not yet investigate; I will submit a bug report later, if I did not cause this myself...

http://fisheye.jboss.com/browse/JBPM/jbpm.3/jpdl/jar/src/main/java/org/jbpm/graph/node/Decision.java?r=1.3
 48 List decisionConditions = null;
  |   :
  | 105  } else if (decisionConditions!=null) {
  | 106    // backwards compatible mode based on separate DecisionCondition
In my setup, database table JBPM_DECISIONCONDITION is empty, but for this Hibernate still creates an empty List. Changing into:
105  } else if (decisionConditions!=null && !decisionConditions.isEmpty()) {
solved my problems. Now both
<decision name="Large quantity?">
  |   <!-- First transition is also the default ("otherwise") branch -->
  |   <transition name="No" to="ship item"/>
  |   <transition name="Yes" to="Make appointment">
  |     <condition><![CDATA[#{quantity > 2}]]></condition>
  |   </transition>
  | </decision>
and
    <condition><![CDATA[#{contextInstance.variables['quantity'] > 2}]]></condition>
work as expected (as noted earlier in this thread, using the 'expression' attribute somehow does not get the condition into the database to start with).
