Hi,
I've been using the old BPMN editor in eclipse. I really like the new BPMN 2 editor with swim lanes and more,
so I installed a fresh copy of Eclipse indigo and installed the BPMN plugin by following jBPM 5.3 Chapter 10 instruction
of http://download.eclipse.org/bpmn2-modeler/site/ http://download.eclipse.org/bpmn2-modeler/site/ After a successful install, I see the BPMN in the
Eclipse preferences, but when I create a BPMN diagram, I get an assertion error:
Could not open editor: assertion failed
With stack trace:
org.eclipse.core.runtime.AssertionFailedException: assertion failed:
at org.eclipse.core.runtime.Assert.isTrue(Assert.java:110)
at org.eclipse.core.runtime.Assert.isTrue(Assert.java:96)
at org.eclipse.ui.part.MultiPageEditorPart.setActivePage(MultiPageEditorPart.java:1065)
at org.eclipse.ui.part.MultiPageEditorPart.createPartControl(MultiPageEditorPart.java:352)
at org.eclipse.ui.internal.EditorReference.createPartHelper(EditorReference.java:670)
at org.eclipse.ui.internal.EditorReference.createPart(EditorReference.java:465)
...
I've tried this install on Windows XP 32 bit, and also on Linux/Ubuntu 2.6.38 64-bit
Using Eclipse Indigo 3.7.2. Both have the same assertion failure.
Given that there are demo's of this plugins in the documentation, this is probably an install issue on my part.
Any idea what I need to do to get the new BPMN editor to work correctly?
Thanks - sam.

[jBPM] - Running a script task and then a rule in a process

Hi
Newbie to BPM/BRMS. I am trying to run a rule after a script task in jBPM 5.3. I am trying to do everything through the jbpm web console, except for the flow group designing, since there is no provision, to my knowledge to design the rule flow in jBPM console. I tried calling fireAllRules() through ksession in the script. I also tried to call fireAllRules() through listener as suggested in another thread here. Never the less I am unable to do it. I must be doing some fundamental mistake here, can anyone suggest me.
Here are the sources:

[jBPM] - Persisted timer event couldn't find work item handler after reload

We are planning to start using JBPM 5.3 in our organization, and started with the following simple process which has the deadline for this month end. Please help !!
Its a simple timer task with 500ms delay & 30 sec period - which sends a reminder email every 30 sec . We need this process to be persistent to be able to restore anytime.
For testing am using Postgres.
1) First am starting a process and after a couple of reminder emails sent out (say after 1 minute) stopping that process to simulate a failure scenerio. Then am reloading the session.
2) When I reload the session quickly within the period (30 sec) - there are no exceptions & able to see timer event kicking off reminders as per schedule. Here is my code :
*setupDataSource(); // postgres datasource*
* Environment env = getEnvironment();*
* KnowledgeBase kbase = createKnowledgeBase("IncidentProcess.bpmn");*
* StatefulKnowledgeSession ksession = JPAKnowledgeService.loadStatefulKnowledgeSession( <sessionId>, kbase, null, env );*
*ksession.getWorkItemManager().registerWorkItemHandler("Email", new SystemOutWorkItemHandler());*
3) *But when I wait more than 30 sec., say upto 5 minutes (in relatime - maintenance may take hours) & reload the session - getting the following exception about WorkItemHanlder which am registering as above. But seems its failing while loading session itself. Also its deleting entry from 'ProcessInstanceInfo' table.*
Hibernate: select nextval ('WORKITEMINFO_ID_SEQ')
Hibernate: select workitemin0_.workItemId as workItemId4_0_, workitemin0_.creationDate as creation2_4_0_, workitemin0_.name as name4_0_, workitemin0_.processInstanceId as processI4_4_0_, workitemin0_.state as state4_0_, workitemin0_.OPTLOCK as OPTLOCK4_0_, workitemin0_.workItemByteArray as workItem7_4_0_ from WorkItemInfo workitemin0_ where workitemin0_.workItemId=?
Hibernate: select processins0_.InstanceId as col_0_0_ from ProcessInstanceInfo processins0_ inner join EventTypes eventtypes1_ on processins0_.InstanceId=eventtypes1_.InstanceId where eventtypes1_.element=?
Unable to execute timer job!
