We have a simple list with a Lookup to another list on a single-line-of-text field.

I customise the form with InfoPath and change the drop-down-list to Combo Box. I set the List ID as the Value and the List Title as the "Display Name". When I test the form and start typing in the Combo Box the type-ahead (custom text / pre-fill / suggestion ) feature doesn't work properly. For example, if I paste a valid value I get the error "Only positive integers are allowed".

It's as if the Combo Box is forcing you to use the mouse to select a valid value and the auto-suggest (and paste) simply doesn't work.

Funnily enough, the paste seems to work in InfoPath Preview Mode, but not in Run Mode (via the Browser).

Any suggestions?

Why don't you make List Title as Value too since ListID is always a number and value is what is used for lookup (and probably what is typed)?

Or, to change Data type in combobox properies to Text(string) if it is Whole Number (integer)
