[BUG] Patch saving null when combo box uses SQL view as the data source

[vladimir84]

Hi,

I have a "weird" bug to report:

I have two combo boxes: one has a SQL table, the second has a SQL View (containing also the id column).

When I do a Patch, the first one's value is saved correctly (I use FirstCombo.Selected.id, because it's a single selection) 

while the other one with the same SecondCombo.Selected.id is saved as blank or null in SQL.

When I use the dropdown with the SQL view, it is patched correctly. 

I tried using the First(SecondCombo.SelectedItems).id, same result.

Is this some sort of limitation on the combobox? 

The tables are tiny, like 10-20 rows. 

I don't get error messages, the Patch is executed successfully.

Hi @vladimir84 

One of the first things I would check is the explicit column selection setting. This may be the reason why PowerApps returns a null ID value. If you turn this off, the stat make a difference?

Yup, that did it.

Also, it was not noticeable in the editor. It was apparent only when the end-user was testing it.
