Hi there,
I have below information in my jpdl.xml file,
decision name="waitDecision">
<transition name="OK" to="wait">
<condition expr="#{responseData == null}"/>
</transition>
<transition to="end"/>
</decision>
If I set responseData a null value and I got exception like below
INFO: exception while executing command mailto:org.jbpm.pvm.internal.cmd.StartProcessInstanceInLatestCmd at 13d638c org.jbpm.pvm.internal.cmd.StartProcessInstanceInLatestCmd at 13d638c
org.jbpm.api.JbpmException: script evaluation error: javax.el.PropertyNotFoundException: Cannot find property responseData
at org.jbpm.pvm.internal.script.ScriptManager.evaluate(ScriptManager.java:130)
It workes in Jbpm 4.0 cr1, now we use Jbpm 4.3. Can we compare null object in jpdl?
Thanks,
Bo
