when my BOOLEAN data field set to be required,
and I'm using a widget:checkbox,
I'm asumming when I do not check the box means saving a zero to the table,
but it goes err telling me the field is a requied field!
and I should check it (save it as 1) before I click on the "save" button!
the required field requires the user choose yes/no,
but now , only yes could be chosed!
if I change the field to allow null,
the field would be not showing in the view mode!
is this an error? or how to solve it?
