Gallery patched text field only updating after changing screens

Posted on by Community Power Pla... Microsoft Employee

This is all based on data stored in a SharePoint list called: Test Checklist USA

The SharePoint list has about 130 lines each with 30 columns.

My app has a Gallery called: G1

In the gallery I have two text input fields: Task Owner and Comments. Both have data loaded by default from the SharePoint list.

When the user changes the Task Owner field in the app, I want to update the comments field to add information about the change and update the SharePoint with the information (new comment and new task owner) so I am using patch in the On Change property of the Task Owner field:

Patch('Test Checklist USA',ThisItem,{'Task owner (prefilled)_E':Taskowner.Text}); //patches the task owner in the sharepoint
Patch('Test Checklist USA',ThisItem,{Comments_E:ThisItem.Comments_E & Char(13) & User().FullName & " (" & Now() & "): Task Owner changed to: " & Taskowner.Text}) //patches the comment field in the sharepoint

When the change happens, the Task Owner is updated but the comment field stays the same. Only after navigating to a different screen and returning do I see the change to the Comment field.

I have tried to patch the Comment first and then the Task Owner like so:

Patch('Test Checklist USA',ThisItem,{Comments_E:ThisItem.Comments_E & Char(13) & User().FullName & " (" & Now() & "): Task Owner changed to: " & Taskowner.Text}); //patches the comment field in the sharepoint

Patch('Test Checklist USA',ThisItem,{'Task owner (prefilled)_E':Taskowner.Text}) //patches the task owner in the sharepoint

In this case, I can see the change to the comment field immediately, but the Task Owner field reverts to the previous value. Again, only after I navigating to a different screen and returning do I see the change to the Task Owner field.

I have tried refreshing the data source using Refresh('Test Checklist USA') after the code but it does nothing.

Is there anything I can do to force the second patched field to update with the new information without having to navigate to a different screen and come back?

Hi @Anonymous,
That sounds pretty odd 😊
If you Reset() the gallery does anything happen?
The gallery should auto-refresh if PowerApps initiates a change to the source - odd that it's doing it for one field and not another...
You can also perhaps try using one patch statement instead of two?

Patch('Test Checklist USA',ThisItem,{ Comments_E: ThisItem.Comments_E & Char(13) & User().FullName & " (" & Now() & "): Task Owner changed to: " & Taskowner.Text, 'Task owner (prefilled)_E':Taskowner.Text })

Kind regards,
RT

Russel you are a genious. 🌟

Your suggestion of using one Patch has done the trick.

I've no idea why patching twice did not work. I knew that the gallery should refresh after the patch but it's like the it does the first patch so fast that the second does not have time enough to refresh or something.

Thank you so very much for your help.

hi @Anonymous ,
It might just be a cache sync-timing thing running two patches straight after each other - but I've run loads of patches in a ForAll and it still updates as expected, so like I said - odd 😊
Glad it's working!
Kind regards,

You want to hear somethig odd-er (is that a word?):

I have a button in the same app that does several patches to other fields in the same source. This button does about 7 patches one after the other.... and guess what? No issues there.
