I have tried this several times now. Can someone try to confirm this issue?
Steps to reproduce, have a sharepoint list with a lookup column with relation-columns. Create a form include the main lookup-field and change it from View lookup to Edit lookup. have a label showing the Form.Unsaved property to confirm while changing the field property in the editor.
I guess there are multiple ways to work around this issue, but I'd like to know if im doing something wrong or if anyone else know of a solution before I start hacking some ugly workaround
Do you mean that the UnSaved property would return true when you change the LookUp field from View Lookup to Edit Lookup within the Edit form control (in Edit mode)?
I have made a test, and the issue is confirmed from my side.
I suppose that the Edit form control would think that you have made some changes within it (this Edit form) when you changed the Lookup field from View Lookup to Edit Lookup, so the UnSaved property would be changed to true.
Currently, I have no idea to work around this issue within PowerApps currently. If you have a better solution, please share here with me.
