When you add a new domain and start adding elements to this domain, the Software Factory will automatically give the first element the database value 0. When using a numeric or integer domain and elements I personally am not a fan of using the database value 0. The value 0 indicates empty and is a value I often use in an ISNULL statement. This is way I prefer starting with value 1 instead of 0.
Currently there is no way to change this default value. I would like this to be a project version setting.
The reason why I would like to configure this is, prevent that co-workers in my team by accident will use value 0 instead of 1 and create an inconsistency.
