Re: [rules-users] [Drools Flow 5.1] Updating a process definition -> Proceed updates running processes
but definition of "Proceed" seems to contradict that: "Proceed: The running process instance proceeds as normal, following the process (definition) as it was defined when the process instance was started. As a result, the already running instance will proceed as if the process was never updated. New instances can be started using the updated process." I mean, if process definition has a different id then this is a different process definition and every method that used to start some particular process based on its id, now needs to be updated to start processes based on new id -> kinda makes the whole idea pointles, doesn't it? And part about version really confuses me then -> it says that "you can use the version parameter to show when a process is updated" which I interpret that I can use version to tell Drools that these are two different versions of process. Seems like either I am dumb; documentation doesn't explain the real use case of updating processes or this feature is not really thought through. -- View this message in context: http://drools.46999.n3.nabble.com/Drools-Flow-5-1-Updating-a-process-definition-Proceed-updates-running-processes-tp2928103p2930258.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] [Drools Flow 5.1] Updating a process definition -> Proceed updates running processes
According to the documentation, updating a process means to add a new version of the process with a different id: "Actually, you cannot really update a process, you can only deploy a new version of the process, the old process will still exist. That is because existing process instances might still need that process definition. So the new process should have a different id, though the name could be the same, and you can use the version parameter to show when a process is updated (the version parameter is just a String and is not validated by the process framework itself, so you can select your own format for specifying minor/major updates, etc.)."

Re: [rules-users] Ruleflow exits before reaching END node?!
After I call ksession.startProcess(processID); I call ksession.fireAllRules(). It appears that the txm.commit() statement in SingleSessionCommandService.execute() method which is invoked for startProcess command somehow leads to removeEventListener(String type, EvenListener listener) which results in the removal of the RuleSetNodeInstance callback of first rule group, therefore, workflow exits at first rule group when fireAllRules is called. Can someone point me in the right direction here? What am I doing wrong here? -- View this message in context: http://drools.46999.n3.nabble.com/Ruleflow-exits-before-reaching-END-node-tp2910473p2930097.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] [Drools Flow 5.1] Updating a process definition -> Proceed updates running processes
Hi! According to http://downloads.jboss.com/drools/docs/5.1.1.34858.FINAL/drools-flow/html/ch04.html#d0e1514 Drools Flow is using "Proceed" strategy by default = already running processes should continue using old process definitions and new processes will be run according to updated process definition. In reality it doesn't seem working this way: I am using persistent session and I have a process with async step. So, whenever a process stops at this step and I update the process definition in Guvnor (and build new package) then process continues with the new definition (I've added simple Action node with system out and change string that is written to system out). I tried to use version parameter in process definition to distinguish between old and new definitions, but it doesn't make any difference. Could someone please comment on that? -- View this message in context: http://drools.46999.n3.nabble.com/Drools-Flow-5-1-Updating-a-process-definition-Proceed-updates-running-processes-tp2928103p2928103.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

[rules-users] Drools flow persistence with Oracle, Could not obtain BTM transaction manager instance
Hello,
I crated a sample application to test the persistent of drools workflow. I
tried the example given in the documentation using H2 Db, everything works
fine.
But when I tried to move to Oracle, I have several problems. I resolved the
bug related to entity names when they are longer than 30, but I still have
an other problem with BitronixTransactionManager
Can you please check if I'm missing some things ?
