minor issue: checkboxes

I have two fields, on a form with the same dataprovider.

one field is text and the other is a checkbox with a valuelist

If I select (in the field with checkbox) two values,
in the other field, its showing the values, seperated with a space.

But if I fill, in a new record, the same values in that field, the other field(with the checkboxes) is not updated

please don’t use a textfield but a textarea.
The separator is an \n (enter) but that will be displayed as a space in a textfield.

ah oke, thanx.
works now!
