Finding all tokens in ProcessDefinition?

[jruud]

I would like to iterate through all the tokens in a ProcessDefinition (in order to print out the token.getId() for each node). However, very likely because I don't understand how the jbpm engine code is supposed to work, I'm only getting the root token back, even when the diagram contains several forks etc. For example, I have tried running the code below on several known-to-be-good process definitions:

ProcessDefinition pd = ProcessDefinition.parseXmlString(xml);
ProcessInstance pi = new ProcessInstance(pd);

...but for example:
pi.findAllTokens() only returns the root token, and:
pi.getRootToken().getChildren() returns null

Any ideas?

Thanks, John

Selfish bump, in case somebody who hasn't read the this yet has some answers...

I think getTokens() and other functions on similar lines return only the active tokens at the particular time. If you want all the current active points for your processDefn, maybe you should look for all the current tasks of ur processInstance. goodluck!

John,

I think you might want to look at the GraphSession class to lookup all process instances for a particular processdefinition. Obtain the graphSession using the JbpmContext.
