[jboss-user] [JBoss jBPM] - Variables in expressions are not deserialized?
I noticed something odd. I was trying to use a decision node which had a
transition that checked a boolean process variable and a default transition.
the syntax of the expression used: #{off}
when running a process instance and toggling the value of off the default
transition is always taken, now i know that the variable is toggled since i
used a global event type node-enter that outputs the value of off to the
console, however i noticed the value is serialized.
so now i was wondering if the value is not deserialized when being accessed in
the expression or something else is amiss.
for now i use a handler, and it works, but i rather use the xml to reduce the
number of classes needed.

[jboss-user] [JBoss jBPM] - Creating new node
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?
