org.jbpm.JbpmException: transition 'tr1' doesn't have destin

[forjbpm]

Hi,

I wrote my own custom node.

For that I wrote my own org.jbpm.ui.model.CustomNode.java
 org.jbpm.ui.contributor.CustomNodeContributor
 org.jbpm.ui.part.tree.CustomNodeTreeEditPart.java
 org.jbpm.ui.part.graph.CustomNodeGraphicalEditPart

classes. made changes accordingly in plugin.xml of jbpm.ui_3.0.8/

I am able to see it in my gpd.
Please correct me if steps I have taken are not right or anything else to be done.

I added my customnode to my processdefinition and deployed this processdefinition.
But I get following error:

Thanks and Regards

I guess it may be because there is no entry indatabase associated with custom-node?

[forjbpm]

ohk!

I realised that I will have to write my own CustomNode class aswell.
something like org.jbpm.garph.node.TaskNode ...
But I am really confused here as to Whether my CustomNode should extend TaskNode or Node?? as If extend Node, Jbdlxmlreaders readTasks and readTask method will not work..
But When my CustomNode extends TaskNode, and when I try to deploy my process with CustomNode.I get following hibernate Exception!

I added CustomNode.hbm.xml and made changes accordingly in Node.hbm.xml, Event.hbm.xml, ExceptionHandler.hbm.xml, RuntimeSction.hbm.xml as well.

I am really far from being a hibernate or jbpm expert.
Any inputs are welcome!

Regards,
