BaseEnum in Form

Hi Community,

I have an BaseEnum "VehicleTyp" with the Elements "Car" (1) and "Truck" (2).

I have a Form "Rentals"

In that Form the EnumValue is not choosen, since I started the values with 1 and 2.

But I'd like to have a text in there, which say's "Choose" but without making a new Element.

I tried to override the initValue() in my rentalTable by saying "this.vehicleTyp = "Choose" ;  but that doesn't make sense at all... just wanted to Show that I am thinking on how I can get it fixed.

Any recommendations ?

Thanks in advance
