I receive the same exact error when my tasks go from claimed to released status (in rapid succession, ie - click claim/release, claim/release, buttons quickly ). I tried creating a modified operations-dsl.mvel with the settings described above. I added this file to my project classpath, but it had no effect. I also tried to directly modify the operations-dsl.mvel that resides inside of jbpm-human-task-war.war, but that did not work either. Here is the error message:
15:30:58,189 ERROR [stderr] (Thread-74) org.jbpm.task.service.PermissionDeniedException: User '[User:'...']' was unable to execution operation 'Release' on task id ... due to a no 'current status' match
Any suggestions on what I could try next? jBPM version is 5.4.0.
Thanks in advance.
