So when trying your suggestions:
I tried using a process variable to specify GroupId for a task. I would like to ask whether you have done this successfully; if so, I will try harder! At present it seems to fail. Note this is jBPM 5.2.
So the name of the group to which I want to associate this task is "managers". I had specified GroupId as "managers" (without quotes) in the task definition and this worked as expected.
I tried using a process variable to specify ActorId. This also clearly worked. Also I believe I found some JUnit test in the source distribution that exercises this.
So I changed the GroupId specification to "#{managersGroup}" plus I defined a process variable with this name.
To assign a value to this variable, I created a Script Node (that executes right after the process is instantiated) that assigns the value:
System.out.println("** ** ** ** ** managers: " + managersGroup + " ** ** ** ** ** ** **");
managersGroup = "managers";
System.out.println(
"** ** ** ** ** managers: " + managersGroup + " ** ** ** ** ** ** **" );
I see the messages written to stdout that indicate the variable has this value assigned.
However, when a member of the managers group looks at their task list, it is empty. Setting a breakpoint, I see that when this method in TaskServiceSession is called:
public List<TaskSummary> getTasksAssignedAsPotentialOwner(finalString userId, List<String> groupIds, final String language, final int firstResult, int maxResults)
groupIds is an empty list (or null, now I forget which).
So please just let me know if you have ever gotten this to work. If you have an example, please show how you specified GroupId.
Thanks!
