Galleries not rendering properly after publishing

[aorphan]

Hello,

I am running into an issue where my galleries load just fine in the designer when I click Preview. However, when I publish and go to Play (run) my app, my gallery on the main screen does not load. However, after I put in search criteria into the search box, and backspace it, then it renders. This problem exists in another screen in another one of our apps. This is recent as these galleries were functioning properly up until recently (noticed today). What changed??

Hi @tahoon ,

Thanks for the reply. We were able to work around the issue. Please note that this is still bugged and this is simply a workaround. I will post the info here in-case anyone else runs into a similar issue.

We have what we call a "master screen" which contains "base" groups of controls and other "pointer" groups which function as pointers/references to the base groups. As mentioned earlier, this is to cut down on repetetive development in PowerApps. We simply copy a "pointer" group to a new screen when we need it. This enables us to modify colors, dimensions, etc. with ease across multiple screens. This "master screen" is never actually displayed at runtime.

The issue appears to be with Galleries. Specifically, the very first gallery that attempts to render. The rows flash for a second, and then are immediately hidden. It's clearly a bug that occurs when the labels reference our "master screen" label properties within galleries.

The solution was to delete all controls from the galleries and make all the labels and icons local to just that screen. Unfortunately, this means we cannot use this design pattern for galleries, at least not for the first gallery that is rendered.

@aorphan If you are still experiencing the issue, can you please try disabling Delayed load in App settings -> Advanced settings and see if this resolves your issue in the published apps?

Hi @_Corey_ ,

The Delayed Load setting has been disabled in our app since the beginning; it does not function properly with it enabled. So it's not that.

Hello,

Sorry for bringing this old post up, but I've recently encountered this as well.

What worked for me:

Add If statement to your gallery ITEMS property.

If(

   IsBlank(searchbox.Value) or searchbox.Value = "",

   Your filter/search code,

   Your filter/search code

)

This way gallery will load the data and you do not need to put search criteria into the searchbox and remove it afterwards.

Hope it helped.

I hate to Lazarus this thread, but has anyone found a reliable fix for this? I have the exact same issue. When I view an app in the preview mode of the editor, my galleries render and work as expected however, when I publish the app, the galleries just don't load until I've entered something into the search box. 

I've tried using the If statement to force the galleries to load, but regrettably the issue persists. This is a pretty infuriating bug as I'm trying to convince people that Power Apps is a viable alternative to other products, but when something simple like this fails to work correctly, that is an uphill battle.

I came here to say that I too am still experiencing this issue. Is there any known workaround or fix?

If you're still experiencing issues, please create a minimal repro app and share it in this thread. There may be different causes for the same issue. It's difficult to know what the cause is without more details.
