There is api to update process variable like: processApi.updateProcessDataInstance(“x”,processInstanceID, 100) but within isInterested(SEvent event) method of event handler i am not getting the reference of processApi. Within groovy script i can easily write like: apiAccessor.getProcessAPI().updateProcessDataInstance(“x”, processInstanceId, 100) but within event handler class i am not getting the reference of processApi.
