Moving jBpm Tokens from one node to another manually in a processInstance, what issues to consider?

Question

For a project I need to move Tokens between nodes that have no transitions between them.

I can set the Node on Tokens and the signal them. This works fine on the root token.

But what else do I have to consider? What will happen when I want to move a token when it's child tokens are still between a fork and a join, or moving a token to a node on a single branch between a fork and a join?

From some experiences I found out that:

• You need to finish TaskInstances when you remove their token from their node.

But I am still looking for a generic way to move tokens in a flow without breaking the flow execution.

I am sure it's not such a uncommon requirement, so how did you solved this?

But I am still looking for a generic way to move tokens in a flow without breaking the flow execution.

Unfortunately this won't be possible. You can move them but have to take the internal working of jBPM into account. Updating parent tokens e.g. in fork/join constructions etc..

I am sure it's not such a uncommon requirement

It is and it is not.

, so how did you solved this?

Staying with the bare minimals and not move tokens in complex constructs.
