Salaboy just for info I think I have found out by looking at the code what I need to do. Fork seems to create new tokens for each leaving transaction. These tokens are added as children to the current token. They are named after the transition name. To gather all of the child tokens underneath the root recursively I think I need to call the collectChildrenRecusively on the root token.
