Problem with unbound BAQCombo control on form customisation

I have a dashboard assembly customisation with a printer selection combo on it to allow the user to choose a printer.
The dashboard contains normal databound grid views, and when the users chooses a row i want the printer value to synchronise with the value from the selected record. They can then “override” this value by choosing from the combo dropdown. I am using a form AfterUpdate event to do this sync.
The problem I am having is that the combo doesn display the value being written to it until the combo is given the focus just once after opening the form. After that it works fine.

Has anyone else had similar issues with unbound controls?


I have a client running into this same problem on an unbound BAQ combo, they’re on 10.2.700. Did you ever find a solution to this?
