ObjectNotFoundException while deleting instance

[jdirksen]

I want to be able to delete processes that have finished or are in an unrecoverable state. I thought this would just be easy just by using:

JbpmContext ctx = JbpmConfiguration.getInstance().createJbpmContext();
 try {
 ProcessInstance inst = ctx.loadProcessInstance(id);
 ctx.getGraphSession().deleteProcessInstance(inst);
 }
 finally {
 ctx.close();
 }

But this doesn't seem to work. When I do this it results in this:

org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [org.jbpm.graph.exe.ProcessInstance#2708]
 at org.hibernate.ObjectNotFoundException.throwIfNull(ObjectNotFoundException.java:27)
 at org.hibernate.proxy.AbstractLazyInitializer.initialize(AbstractLazyInitializer.java:65)
 at org.hibernate.proxy.AbstractLazyInitializer.getImplementation(AbstractLazyInitializer.java:98)
 at org.hibernate.impl.SessionImpl.bestGuessEntityName(SessionImpl.java:1701)
 at org.hibernate.impl.AbstractQueryImpl.setEntity(AbstractQueryImpl.java:564)
 at org.jbpm.db.GraphSession.deleteProcessInstance(GraphSession.java:329)

Any idea what I might be doing wrong? It's strange that I can load the instance, but I can't delete it.

Hope someone can help me with this.

Well just ignore my post. I've just checked what's stored in the database, and the process instance really isn't there.

From my UI I passed in the id of the process definition not of the instance I was trying to delete.

Keep up the great work, it's been really interesting integration jBpm into our current project, good intuitive API and well working library.
