PowerApps Form Returning Blank View Form on Gallery Selection

[Anonymous]

I have a problem with a PowerApps Form i have been building,

Some of the items are displaying a blank view form on selecting an item from a gallery

I have tried selecting the gallery item I have also tried passing the item between the gallery and the form
I should note that this only happens on several of the records and not them all
This missing item is at the form at the top

Form Item

If(Value(DCFormID) > 0, First(Filter('Document Management Team Request', ID = Value(DCFormID))), CurrentItem)

Gallery selection

Select(Parent); ClearCollect(REItem, First(Filter('Request Evaluation', Request.Id = Gallery2.Selected.ID))); Set(CurrentItem, ThisItem);

I have been stuck on this all day

To note that if another record is selected then everything works ok


As you can see this record is working as expected.

Anyone have any ideas as i cant find any major inconsistencies within the data

Thanks in Advance

hi @Anonymous ,

Instead of using CurrentItem in your Form Item try to do a lookup to this record:

If(Value(DCFormID) > 0, First(Filter('Document Management Team Request', ID = Value(DCFormID))), Lookup(Datasource,ID=CurrentItem.ID))

Best Regards,

Anthony

Thanks @Anthony_Dob That was what i was doing in the original instance and i changed it to pull the record into a variable in the first instance,  both ways have the same results.

i.e. some records return the form and some just appear blank.

and i should also note that the same issue is happening with Gallery.Selected or doing a lookup on Gallery.Selected.ID

I should note that the list currently has about 300 records and i have set the limit to be 2000 records.

The True part of your IF statement, is this the same type of record as the False part? No differences there? Otherwise that might be causing the problem

Hi @Anthony_Dob  yes they are exactly the same,  the true part is only checking if an ID has been passed into the system previously,   again this is working for some records and not others.

We went through testing previously and this issue didn't occur,  it seems as though for some of the records something is falling over but i am not getting an error anywhere the only thing i am getting is a delegation warning against ID.  everything just appears to be blank with nothing showing up at all.

When i try to change the form to Edit the same thing is happening i.e. it turns blank rather than getting the no item error.

You're trying to use two different data sources in the item property of the form. From what I know you can't do this cause you'll run into binding issues, the item loaded should be the same data source. Not sure the logic behind the item property if the ID should always be > 0? What's the point of the IF and the other data source?
