[jbpm-users] [JBoss jBPM] - Error while completing task
Hi,
Following error is thrown when last task in a process is completed.
This happens only for the last task before the process is ended and not for intermediate
tasks.
Also, should i explicitly set the value of result in variables? something like this?
I'm assuming this to be only in case of sub process and is not needed even if task has
multiple transitions?
taskService.setVariable(taskImpl.getDbid(), "result", action);
Code & Process Definition:
| taskService.completeTask(taskImpl.getDbid());
