Getting error with trying to change visibility of a screen

Posted on by Community Power Pla...

I'm using a collection to determine if the a screen should be shown. I've tested that the given value can end up in the collection but it's giving me an error that it will always navigate away and won't allow me to set that.

ERROR: "Navigate cannot be used here since it would automatically always navigate away from this screen"

MY FUNCTION in the onVisible attribute of a screen: If("Transmission Region" in Screens, false, Navigate('Materials Inspec Screen'))

the idea was that if it wasn't in the collection to move on to the next screen.

@eka24
"Transmission Region" is the current screen and screens is the collection of all of the selected screens.
so, if the current screen isn't in the collection it moves on to the next screen which would be "Materials Inspec Screen"

Hi @Anonymous

The problem you're facing here is that it isn't possible to call the Navigate function from the OnVisible property of a screen.

There are more details in the post beneath, including the following workaround.

https://powerusers.microsoft.com/t5/Building-Power-Apps/Why-we-can-not-use-Navigate-in-OnVisible/td-p/73148

There is a simple workaround with using a button or any other control with OnSelect property and calling the Select(YourButton) to execute the Navigate() function.

For example, add a button and change its OnSelect to:
Navigate(MainMenu_Screen,None)

Now in the OnVisible property change your code to this:

UpdateContext({LoadingText:"Searching for your name..."}); Set( _UserProfile, Office365Users.MyProfile() ); If( !IsBlank(_UserProfile), Select(Button1), UpdateContext({LoadingText:"Failed to load your profile. Please restart the App"}) )
