Attachments get lost when passed to a context variable

[Paul_Cbl]

Hi,

I have an application with two screens. The first screen shows a gallery of items retrieved from a SharePoint list.

The second screen shows details of the selected item in the first screen.

In the first screen, I can access the attached files for the row just fine (accessing First(ThisItem.Attachments).AbsoluteURI works just fine for example.

Now when I navigate to the second screen like so: 

Navigate(ItemDetails; ScreenTransition.Cover; {selectedItem: ThisItem});;​

I can access all properties of `selectedItem`, except for the Attachments. PowerApps behaves as if this property didn't exist at all on selectedItem.

Why does this happen? What do you think is the best solution to access the attachments on a second screen?

Thank you

Hi @Paul_Cbl ,

Yes, the Attachment field can't be saved in Variable or Collection, please reference it directly from the SharePoint list. The solution is save the selected item ID to the variable, and use LookUp function to retrieve the record.attachments field based on the ID.

Navigate(ItemDetails; ScreenTransition.Cover; {selectedItemID: ThisItem.ID});;​

First(LookUp('SP list', ID=selectedItemID).Attachments).DisplayName

Hope this helps.
