[jbpm-issues] [JBoss JIRA] Updated: (JBPM-2570) Problem with Fork/Join

[ https://jira.jboss.org/jira/browse/JBPM-2570?page=com.atlassian.jira.plug... ] Alejandro Guizar updated JBPM-2570: ----------------------------------- Description: I am having some problems with the Forks / join when I have assigned swimlanes, and I can't figure it out yet. Perhaps you can think of something. I have a simple graph with 5 tasks. Task 1, Task 2 Task 3 Task 4 and Task 5. I also have a fork and two joins. The situation is like this: The process starts and the first thing it does is to launch a Fork that runs 3 tasks, Task 1, 2 and 3. which have different swimlanes associated to them. of these 3 tasks, Task 1 and Task 2 converge on Join 1, which continues the thread to task 4. Task 4 has a transition to Join 2, which is responsible for closing task 3 (originally launched with Task 1 and Task 2 but not yet closed). Once task 3 and 4 finish, the flow should continue. Theoretically, it seems to be fine. Practically, the Fork / Join work if I do not assign swimlanes. But when I assign different swimlanes to the initial tasks T1 T2 and T3 the process gives problems, it won't let me close the first fork. Because Task 1 and Task 2 have different swimlanes (it is giving me a foreign key error between the active task table and the swimlane table). From what I see, it wants to delete from the active task table after finishing a task, but it does not delete from the swimlane table, thus the foreign key error emerges. This is the error. Could not delete: [org.jbpm.pvm.internal.task.SwimlaneImpl # 164]; nested exception is org.hibernate.exception.ConstraintViolationException was: I am having some problems with the Forks / join when I swimlane assigned. and I give it right yet. Perhaps you can think of something. I have a simple graph with 5 tasks. Task 1, Task 2 Task 3 Task 4 and Task 5. I also have a fork and two joins. The situation is like this: Start the process and the first thing is to launch a running 3 tasks Fork, Task 1, 2 and 3. swimlane which have different partners. of these 3 tasks, the Tarea1 and Tarea2 Join converge on the 1 that the join 1 continues the thread to the task 4. Task 4 has a transaction to Join 2, which is responsible for closing the task 3 (originally released with Tarea1 and Tarea2 but queaun not closed). When the proposal in Task 3 and 4 should continue to flow. Theoretically, it seems to be fine. Practically, it works the Fork / Join if you do not assign swimlane. But when the 3 swimlane assign different initial tasks T1 T2 and T3 gives problems, it is leaving me to close the first Fork. Because Tarea1 and have different Tarea2 swimlane (is giving me an error of foreign calve between the table of active jobs and the swimlane). From what I see, you want to delete the active task table after finishing a task, but not deleted from the table should swimlane and emerges as the foreign key error. This is the error. Could not delete: [org.jbpm.pvm.internal.task.SwimlaneImpl # 164]; nested exception is org.hibernate.exception.ConstraintViolationException Provided human translation :) The process definition is somewhat esoteric, the kind you see in BPM demos to show how twisted your model can be, but rarely in real usage. I'd suggest a second fork be introduced after Fork 1 but before Task 1 and Task 2 to correctly balance Join 1. The current Fork implementation won't cope with the process definition as stated in the description. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
