Hello all
I read the documentation at http://docs.jboss.com/jbpm/v3.2/userguide/html/. It
mentions that nodetype node can have customized behavior when it comes to
creating new execution paths in the form of a token, also this behavior must be
programmed in an action handler.
The node behavior I want to create is when a token arrives, a new token is
created and passed on to a leaving transition, the arrived token is passed over
the default leaving transition (eventually i will be expanding this to allow
for any number of new tokens and any number of leaving transitions).
token token
-----> [Split] -----> ...
| new token
\-----------> ... -> [end-state]
I implemented this in the execute method like this:
Token newToken = new Token(executionContext.getToken(), "split");
ExecutionContext newContext = new ExecutionContext(newToken);
executionContext.leaveNode();
newContext.leaveNode("split");
When I run the process I can see that the new tokens are produced and indeed
arrive in the end state all seems to be in order as far as I can tell.
Except that calling
JbpmContext.getGraphSession().deleteProcessInstance(theInstanceContainingSplitId)
(this I use to remove the process from the database while testing) throws a
database constraint exception on the foreign key for the token table. Is this
because I am doing something wrong while producing the new tokens or is this
some bug?
