I have the following issue: Depending on a checkbox in task X being checked or not, task Y should be activated or not. Modelled in CMMN, you can place an entry criterion (checkbox = true) on task Y. But by that, task Y only activates when task X is complete. Respectivaly the value ‘checkbox=true’ is only in the payload when task X complete. In my use case it is crucial that task Y activates when task X is saved and not only when it is complete, as user should/can not be forced to have task X completed before being able to do task Y. Does anybody know if this possible to model in CMMN (or BPMN) and if yes, how? Thanks and cheers, ---

That’s currently not possible. The upcoming version will have a new concept called ‘variable listeners’ that will allow to do this. ---
