--------------------------------------------------------------
Hi guys,
With JBPM 5.1, if I define a Service Task with no interfaces (it's legal in BPMN2) -for instance using the new BPMN2 eclipse editor- this is not accepted.
Indeed, when I load the resource in the knowledge base, I see:
java.lang.IllegalArgumentException: No interfaces found
at org.jbpm.bpmn2.xml.ServiceTaskHandler.handleNode(ServiceTaskHandler.java:51)
at org.jbpm.bpmn2.xml.TaskHandler.end(TaskHandler.java:188)
at org.drools.xml.ExtensibleXmlParser.endElement(ExtensibleXmlParser.java:414)
That behaviour it's very simple to reproduce (and the ServiceTaskHandler code is very clear) so I suppose that it's not a bug.
Anyway, in my opinion this is not correct. In JBPM/Drools, I can set which WorkItemHandler I want to use for each Task "type".
So if I want to have serviceTasks that are based on other informations (and not the interface) I cannot do that using a Service Task.
Ok, I know that I can do that with the "generic" task, but I'd like to use a Service Task (It's the correct task from the modeling point-of-view).
Why this behaviour has been implemented?

[jBPM Development] - JBPM Custom Editor ----- For parameter mapping

Hi All,
I am currently facing a problem in custom editor.
I want to create a custom task editor where user should be able to do parameter mapping similar to whats shown in prperties tab.
The current dialog from properties section ask user both parameter and process variable. I want to create a custom editor where I will show use parameter and user needs to select process varia ble from list,
It seems that I can take only Work and workdefinition in custom editor. I have looked into the *org.drools.eclipse.flow.ruleflow.view.property.workitem.WorkItemParameterMappingDialog* and feel that workItemNode used in that class should do the trick.
Is there any way to get *org.jbpm.workflow.core.node.workItemNode* in custom editor*?*
Regards,
Ashish

[JBoss Transactions Development] - Remote txinflow: XID changes

Just to get the ball rolling on this part of this design discussion, we need to consider how best to update XidImple to allow the recovery manager to detect transactions managed by this node as the status quo would leave transactions that flowed to remote servers un-recoverable as the recovery manager checks the node name encoded in the XidImple would not have the same node ID as the local server. Also, branches passed to the XAResources would be the same branch and this could have undesired behavior in the XAResources.
David suggests one approach:
David Lloyd wrote:
You could however use integer packing to make more room; in such a scheme, the bqual bits which identify the node would still be an integer sequence but would work like this:
For this to work you'd have to treat 0000 as a special padding sequence for the case where only one nybble of the last byte is used. Thus giving:
0000: padding
0001-0111: resources 0-6
1000 0000-1011 1111: resources 7-70
1100 0000 0000-1101 1111 1111: resources 71-582
etc.
Node names are currently recorded as variable length Strings, one option is to cat the new node name onto the end of the bqual resulting in:
Xid {
formatId
gtrid - uid + nodename
bqual - [uid (for the sequence number) + jndi name] + [nodename of the subordinate]
}
This will keep the bquals unique between TMs and will facitilitate recovery of this transaction.
To be continued...
