OnStart - Am I doing something wrong?

[hilary_stoupa]

I'm using the web version of the studio.

In OnStart, I want to create a variable with the User().Email as a value - I was hoping then I could use that in a filter for a data source instead of directly using User().Email, as that is apparently not delegable (based on the blue info dot and message).

But my variable doesn't seem to be set on start.

Function:

Set(CurrentUser, User().Email)

I put a label on the form with a value of CurrentUser, run the app, and the variable doesn't appear to have its value set.

I also tested using a Navigate function, but that also didn't appear to do anything - on start, I remained on the same screen.

Any ideas where I'm going wrong?

Hi, I did the same and it worked for me. You need to reopen the app in ordert for the OnStart to be triggered.
I use the desktop Studio.
PS There is another very good reason to cache the user value in a varible, that otherwise the function gets called every time it is used and slows performnce.

Thank you - the trick was to reopen the app, which I hadn't realized.

Hi, I had been trying to accomplish this in 2020; but as long I am on the studio works but when I preview or publish the app, it doesn't load any information became a big blank space. Any idea?
