Process State

[aksharma]

I am trying to test a Process definition with process state (subprocess).

The execution enters the subprocess but fails in the sub process ..Any clues ..



ibernate: select variableac0_.SCRIPT_ as SCRIPT8_1_, variableac0_.ID_ as ID1_1_, variableac0_.ID_ as ID1_12_0_, variableac0_.VARIABLENAME_ as VARIABLE2_12_0_, variableac0_.ACCESS_ as ACCESS3_12_0_, variableac0_.MAPPEDNAME_ as MAPPEDNAME4_12_0_ from JBPM_VARIABLEACCESS variableac0_ where variableac0_.SCRIPT_=?

i've got the same problem when i trigger the signal method in the processState node.
it seems that in the leave method of class ProcessState, the parameter executionContext got a null value for the subProcessInstance.
im a rooki using jbpm please post you got a solutioon for this.

thanks josch

hi,
no nothing of that, just a customized assignmenthandler in the swimlane of my subprocess

snippet of my main process definition

<start-state name="start">
 <task name="taskKonfigNeuanlage" swimlane="SystemMandant"></task>
 <transition name="" to="Konfiguration-Eingabe"></transition>
 </start-state>
 <process-state name="Konfiguration-Eingabe">
 <sub-process name="konfigEingeben"/>
 <transition name="" to="KonfigurationFreigeben"></transition>
 </process-state>

...

and the subprocess

<process-definition xlmns="urn;jbpm.org:jpdl-3.1" name="konfigEingeben">
 <swimlane name="Techniker">
 <assignment class="com.siemens.websolutions.ams.test.DefaultAssignmentHandler">
 <taskName>konfigurationEingabe</taskName>
 <roleList>techniker</roleList>
 </assignment>
 </swimlane>

 <start-state name="startKonfiguration-Eingabe">
 <task name="konfigEingebenTask" swimlane="Techniker"></task>
 <transition name="" to="KonfigurationEingabe"></transition>
 </start-state>

 <task-node name="KonfigurationEingabe">
 <task name="Asset" swimlane="Techniker"></task>

...

thanks for reply
Josch
