Problem using Event Structure

[pparo]

Hello,

Attached is my application where the user can drive the states transition trough buttons in the window.
I'm using event structure to monitor the buttons but there's a specific condition where it doesn't work properly.
If I push the buttons in the following sequence: "GO TROUBLESHOOT" and "PASSED", the buttons "RUN AGAIN" and "EXIT" seems to be locked in the next window.
However everything is OK if I push "FAILED" instead of "PASSED". I've already checked the option Lock Front Panel in the event structure but it doesn't affect the previous behavior. I really don't understand what is happening.
Thanks in advance for any help.

Hello.
Unfortunately, I was unable to run the VI you sent, since Test Module General Error Handler.vi has a broken arrow when I open it in my computer (I don't know why). However, I ran into a very similar situation when I was trying to program an application using state machines and event structures as you are doing in the VI you attached. After some investigation, I noticed that the execution locks if there is an event for an event structure that is in a state of the state-machine different to the current state. So, my guess is that when you press "Passed" your state machine is not going to the state you think it is going. Put a probe at the output of the shift register where you store the current state to verify that this is so. I don't know if this is the
problem, but if it is, that probe is an easy way to get to the root of it.
