Hi all I have a requirement as below: ![alt text][1] In here i have two process which send two different signals, When one signal has been started, it will wait (by a system task) until the other signal also be started then two signal will join to do another logic. Signal 1 and Signal 2 can be started randomly. If i implement like above picture, the system task will not join to continue when two signals has started, started already, i guess it's because of there is two different cases. Am i correct? Another approach could be using a boundary signal event. But is there any other approaches which is better than it on ivy? i see in ivy we also has other elements like *wait*, *Call & Wait*,... Can i apply it for this requirement. Thanks a lot [1]: http://answers.axonivy.com/upfiles/Untitled_850woR8.png
