Custom Property Expression

gdford — Fri, 19 May 2023 22:17:27 GMT

I had an odd thing happen with an expression.

It just stopped working.
In the expression editor it gave no error.
In the object properties is said:

I opened a backup copy of the file and copied the expression and then pasted it into the project where the expression had stopped working and then everything was fine....fixed like new.

Any thoughts anyone????

Did you figure it out? Way beyond me (novice AC programming at this point, especially with a nested conditional? ;-0) . I’ll offer a thought gained from a few other experiences over the years with apps: maybe the session did not load an ID or value on start or lost it at some point. Then, the subsequent ‘open’ loaded it, allowing the expression to ‘evaluate’.
