How to stop second branch of a converging XOR gateway?

[mvermand]

Hi,

Given the following flow:

The split gateway is of type AND.

The join gateway is of type XOR.

I thought that if one of the branches passed the xor join gateway, the second would not pass anymore upon completion, but now I found out that it does...

Once when the timer expires and once when the event arrives.

The "Process" node is executed twice (given that the event does arrive).

I wanted to use such construct to block the event when the specified time had passed.

The "Process" node then can operate on a variable (not) set by the signal event handler.

How can I achieve such control of flow?

Thank you!

hi, you can add boolean variable like "processStarted" to process. Set It true, In "On Entry Action" of "Process" node. And check it variable after each event with Exclusive gateway (XOR).

you could enclose these gateways and events within embedded subprocess and use terminate end event to complete the subprocess as soon as any of the paths reach the end event, moving up from subprocess to the main process for continuation.
