Hello,
When playing around with jpbm I stumbled onto this problem for which I can't
find a decent solution (to be honest I think it cannot be handled with my
version of jbpm - which is 3.1.1).
The problem is as follows:
When deploying a process definition A which has another process definition B as
sub process (using processState node), you need to first deploy a new version
of B before deploying A. Otherwise A will still be linked with an older
version of B.
The reason for this behavior is that the link with the subprocess is resolved
at deployment time, so if A is deployed first it will be linked with the
existing (older) version of B in the database. Deploying B afterwards will not
resolve this, so A is stuck in this case with the older version of B.
That's OK for me. Furthermore the resolving behavior can be tweaked by
providing a custom SubProcessResolver.
Suppose that you have a recursive process definition, i.e. the process
definition A has itself as subprocess. If I Deploy A, it will resolve the
subProcess, which will make a link to the older deployed version of A! And
this is not what we want, it must refer to the new deployed version!!
Same problem arises with other recursive process definitions f.e. A containing
B, containing C which contains A again.
When looking at the code I see that there is something which handles the case
when a recursive process definition is deployed for the first time
(ProcessState.java).
| // in case this is a self-recursive process invocation...
| if (subProcessDefinition==null) {
| String subProcessName = subProcessElement.attributeValue("name");
| if (subProcessName.equals(processDefinition.getName())) {
| subProcessDefinition = processDefinition;
| }
| }
This will work since no A is deployed yet, but as soon as an A is deployed the
subProcessDefinition will be filled in by the resolver (with a wrong old
deployed A).
How to solve this problem? Is there a way to deploy A and stalling the
resolution of subprocesses?
thx,
Olivier.
