Process engine hangs at inclusive gateways

Flowable Engine
1

We have modelled a wizard as FlowableProcess, where each step of the wizard is modelled like humanTask. The user can go back and redo previous tasks. If he choses so we complete the abandoned tasks but set local variable in the abandoned execution so it can exit from the process.
All works as expected up until we complete the “enterAddressData” step where the process hangs at the gateways (see debugger screenshot).

We have no explanation for this behavior. Could please anyone share why a process is working up until a point and hangs at the gateways. Is there something that causes the gateway to wait something?

An inclusive gateway will wait until 'there is no path anymore to the inclusive gateway that can reach it, disregarding conditions on sequence flow). Which is, I assume, what is happening here. Is there a reason why you’re using an inclusive gateway. From the screenshot you shared, it looks like most can be replaced by a simple exclusive gateway?

Thanks for the clarification as this is not so easy to understand. Basically our use case is to model onboarding process, where in certain steps the user is allowed to go back and re-do previous steps.
So this solution came to mind where past tasks (screens) get reopened and we try to abandon (complete) the tasks that are deemed invalid (by setting local variable and exit condition).
This way when you complete Task 1 → next you got Task1 and Task2 open so you can complete either of them. Choosing to complete again Task1 would again reopen Task2 with the new context from Task1. Since we want to “abandon” the old Task2 we set local variable (exit) and complete it before Task1 and count on the GW to exit the abandoned execution’s.

Is there more elegant way to achieve this ?

I agree. However, it’s implemented like it’s described in the BPMN specification.

With the scenario you describe you indeed get quickly into a cobweb of sequenceflow going left and right from sequence flow. Sadly, not much to be done about it.
These kind of use cases are easier expressed in CMMN typically, where tasks can have guards (=sentries) based on variables that can activate or complete automatically.
