At some point, i have to derive by the rules if any other sub-processes have to be created. Since jbpm provides an option to create only 1 subprocess at a given step, I'm openning subprocesses programmatically, i.e. in *CreateSubprocesses* activity handler:         {code}        //calculate groups to assign to a swimlane          taskAssignees = ...;                       assigneeGroups.put(SharedConstants.KEY_SWIMLANE_CANDIDATE_GROUPS, taskAssignees);                        ProcessInstance processInstance = executionService.startProcessInstanceByKey("subprocess_1", assigneeGroups);    {/code} Again, all of the above is done in an activity handler of the process that has just been instantiated and hasn't been saved to db yet. Here's a shortened version of my jpdl: {code:xml} <process key="main" name="main" xmlns=" http://jbpm.org/4.3/jpdl http://jbpm.org/4.3/jpdl">       <start g="5,23,48,48" name="start">       <transition g="141,46:-88,-15" name="open.case" to="Create sub-process"/>    </start>    <state g="306,193,148,52" name="Wait For Update">       <transition g="-23,-24" name="end" to="end1"/>    </state>       <custom g="239,26,138,52" name="Create sub-process" class="*CreateSubprocesses*">       <transition g="484,52:-108,-17" name="to-split-paths" to="Wait For Update"/>    </custom>   <end g="566,493,48,48" name="end1"/> </process> {/code:xml} and one of possible sub-processes (simplified): {code:xml} <?xml version="1.0" encoding="UTF-8"?> <process name="test" key="test" xmlns=" http://jbpm.org/4.3/jpdl http://jbpm.org/4.3/jpdl">    <swimlane candidate-groups="#{assigned.responsibilities}" name="assigned-group"/>    <start name="start1" g="16,21,48,48">       <transition name="to task1" to="task1" g="-17,-20"/>    </start>       <end name="end1" g="219,17,48,48"/>       <task name="task1" g="96,16,92,52" swimlane="assigned-group">       <transition name="to end1" to="end1" g="-20,-19"/>    </task>    </process> {/code:xml} -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/543442#543442] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
