Exporting problem

After closing and reopining Servoy (beta6) I got the import to work, but I imported a tab file and it kicked out an error saying there was a null value.

Is there anyway to make this not an error? This probably has a lot to do with the backend (firebird) but from a user’s experience, they’ll often need to import simple lists of contacts and sometimes the home city, for example, won’t be filled in.

Thanks.
