Hi everybody,

i found many interesting points according to collapsing pools and show the in- and outcoming message flows to a black box (http://en.bpmn-community.org/tutorials/5/). My question is, it is although possible to collapse lanes, which are neasted in a pool. But what happens with the sequenz flow? I do not mean a collapse sub-process.

Thanks a lot in advance James

That's not possible. I can also not think of a desirable case. If a role is involved in a process and is worth mentioning in the model then put him in together with his contribution (performed activity).

Indeed, the sequence flow semantics would raise a lot of issues and make all our nice Model Verifikation tools cry:)

Sometimes, you might want to hide information to reduce complexity. Fair. I propose to decompose the processes and build a highlevel model to glue them together.

Hope that helps, alexG
