Error Message when Related Action is no longer visible

Question

I have a related action accessible to a number of users. The action will be hidden upon execution. If two users open the summary page at the same time, the first one to click it will be able to execute the action. Although the action is still visible on the second user, he/she will now get "An error Has Occurred. The specified <RECORD> related action does not exist or you do not have permission to view it". 
 Is there a way to handle this error to provide a better message? 
 Thanks.

What logic are you using to hide the related action from the second user to click it? Instead, something I've done successfully in the past is allow the user to click it if they still see the link/button, and do that logic in a gateway early on in the process. If it fails, route them to an alternative task explaning that the action is no longer available, and upon clicking the submit button they'll be routed cleanly back to the related action list / record dashboard they started from.

That's one of the reasons I asked what logic you're using - without knowing some more details I can only guess as to how you're disallowing visibility of the related action after the first user initializes it. 
 I suppose my first guess is that you're setting a DB value when the first user initiates the action. In this case, you simply need to add a query at the start of the process instance to check for the most up-to-date value and base evaluation of the subsequent gateway from that.

Yes - my whole point here is that you would reconfigure the visibility setting such that users are not prevented from having access to the related action itself (at least if they happened to load the related action list in time to already see the button/link). Then you can reroute the user to something as user-friendly as you feel like designing.
