Need Help for Sub-Process

[tom_sri74]

Hi,

In my machine i installed jbpm-gpd-for-eclipse-3.0-beta1.zip and also overide jbpm jbpm-gpd-site-3.05 (pluggin and feature)

In eclipse (Process Definition) i can see the component
1. Select
2. Marquee
3. Start
4. State
5. End
6. Fork
7. Join
8. Decision
9. Node
10. Task Node
11. Transition

I don't see for process-state, synconize and sub-process...

How i can create the process-state, I want to work in Process associate with some other process (for eg sub-process)

Please help me in this regards
Thanks for advance
Srikanth

You have to do it in the XML. There is no GUI component for the sub process.

I did some example code.


Parent Process

<?xml version="1.0" encoding="UTF-8"?>

<process-definition name="mainProcess">

 <!-- SWIMLANES (= process roles) -->

 <swimlane name="customer" >
 <assignment expression="user(customer)" />
 </swimlane>

 <swimlane name="operator1">

 </swimlane>
 <!-- NODES -->
 <start-state name="MainProcessStart">

sub Process

</process-definition>

After deploying the both par in mysql and i experiment in JBPM application i am able to see the MainProcessStart Task, when i click that task and enter two fields value and click SaveAndClose. After that it's not coming in "Mainstate1" what is wrong. if i removed process-state it is working.
Any Idea please.


Thanks & Regards

Hey atleast some body let me know i am in right direction..

[enazareno]

If you are using Jbpm 3.02 change your process-state name to subProcess. There seems to be a bug in that version but I cannot confirm since I already upgraded to 3.1. There is already some post in that I can't recall.

Also, for task-nodes use task-node, not state. Maybe it will work but task-nodes are much more appropriate.

Now it's creating the subprocess. what i did i download jbpm 3.02 and jbpm starter kit 3.02, Previously i use to worked in jbpm 3.1 alpha 1. this is not creating the subprocess i don't know why.

but one issue after creating the subprocess i am getting message in server given below:-

Here is the different code

Please let me know what i did in right direction. or i need to some other logic...

It seems its a UI, probably a jsp related problem. I think I've already seen that issue somewhere, just check some posts here. Use the search facility in the post. Tip: check the database for entries, if there are values in there that seems to be correct, then you are on the right track.

WARNING: Component _id13 just got an automatic id, because there was no id assigned yet. If this component was created dynamically (i.e. not by a JSP tag) you should assign it an explicit static id or assign it the id you get from the createUniqueId from the current UIViewRoot component right after creation!
