Hi,
I have only script tasks in my workflow and am using multi-instance. I observed that the following exception is thrown many times after the script tasks have successfully executed.
Oct 25, 2011 1:18:47 AM org.activiti.engine.impl.interceptor.CommandContext close
SEVERE: Error while closing command context
org.activiti.engine.ActivitiOptimisticLockingException: ExecutionEntity[13] was updated by another transaction concurrently

Since my delegate script tasks are successfully completed, I would like to ignore this exception (do not want to retry which re-executes the script tasks). I inserted an interceptor, caught this exception? I tried to ignore it but found that i need to delete the job. Is there a way to delete a job that just threw ActivitiOptimisticLockingException?
// my interceptor
public <T> T execute(Command<T> command) {
try {
// try to execute the command
return next.execute(command);
} catch (ActivitiOptimisticLockingException e) {
// here command has job id but there is no accessor method.
// if i could get jobid, i could delete the job
// next.execute(new DeleteJobsCmd(jobid);
}
}
