Capturing unhandled errors in JavaScript Control Add-ins
Not that I am saying it’s a good thing, but trial and error is a fairly common approach to debugging in the NAV world. We’ve all done it. Heck, even with the comprehensive testability framework built in, we all still do it more often than we’re happy to admit while sober.
But the overlord of trial and error in NAV is development of control add-ins in JavaScript. JavaScript itself is making it difficult in the first place, and then integration with NAV makes it even harder.
There is one situation in particular that’s adding a cherry on top of all of problems, and it’s the creepy “A script error has occurred” error message. It’s the equivalent of the BSoD.
