@lidor_dayan ,
OK I have eliminated all the things I thought may be wrong - if the Update is (as you posted)
{
Value:
Coalesce(
DataCardValue15.SearchText,
DataCardValue15.Selected.Value
)
}
and you have cleared the selected item from the Combo Box and have nothing in the Search Text (as well as having Formula Level Error Management turned on) and you are (I assume) using SubmitForm to save the record, then it certainly should clear the field in the data source. I have a feeling however you may have found a bug here - to test, put this in the Update and see if it clears the field
DataCardValue15.Selected
