PowerApp Designer calculation problem for Height / Width

(0) Share

Report

Posted on by Michael-Megel

When I open my Canvas App in the PowerApp Designer I have several layout issues:

Variables App.Height / App.Width are not calculated / resolved
Power App Components don't display controls at the right calculated position

The example shows the usage of the App.Width ... should be 1366

Value is correct shown:

When I enforce a recalculation by changing the value (e.g. "+ 1"), the value is assigned correct and the control is displayed:

When I reload / reopen the Designer, unfortunately everything is gone and my PowerApp is not longer editable.

On the other hand, the last published version looks as expected:

How can I fix the problem?

Hi @Michael-Megel ,

I'm not able to replicate this. Can you share more about your setup? I attached an app with a component whose width is set to App.Width and it appears correctly upon opening in the studio.

Let me know what additional steps are needed to reproduce your situation.

Hi @Michael-Megel , Does it work if you do save as of the app after fixing the rules and try to open the app again? Also could you please confirm the session Id again when the issue occurs? I wasn't able to see any data for the shared session Id. Thanks.

Hi @Mr-Dang-MSFT,

I have imported the last working version into a fresh CDX Demo-Environment. The designer shows the same behavior. The App Checker does not provide information about issues:

I can show you the problem or share my demo environment.
If you are interested, you can contact me by mail or teams: michael.megel@cosmoconsult.com

@Michael-Megel , Under Account tab, you will find Diagnostics and session details below it. Just share information from there.

Hi @ShantanuP ,

My current Prod-Environment Designer Session details
Session ID: 32842644-54f2-40d6-bfa4-36d953d540fa
PowerApps 3.20065.16

Currently I have restructured in this environment some formulas. But I have still issues with my Custom Component "Menu".

My Custom Component layout is correct displayed in designer:
I use a Gallery Control to display this icons:

the result in my screen view is:

This means, the X location of the 2nd Gallery (My Environments, New Environment) is calculated wrong. The formula in the custom control is: X := edActionsMenu.Width
and edActionsMenu.Width is:

I guess there is anywhere a hidden calculation issue, which causes the wrong calculated Custom Component. I found out, when I fix the Custom Component by invoke "recalculation" of width, the layout in Screens is "better" until next Designer Session.

@Michael-Megel , Does it happen if you use any previous version of the studio? You can select previous versions from "Change authoring version" under Accounts tab. I want to understand if this is a regression.
