[jboss-user] [JBoss jBPM] - Token.signal() throws Exception from FieldInstantiator

[SidKennedy]

Hello again :)
I have another problem. I have a processdefinition and I added some other xml-tags to a node for example as I thought that this is possible. Then I instantiate the definition, go for the RootToken and invoke signal() to start my process like this:

  | process.getRootToken().signal();
  | 

but the following exception is thrown:

I don't know what I can do with that information because the process is completed successfully. But I don't like exceptions as you can imagine ;) Do you have an idea what I can do?

greets
