6625	Overriding the default field types in a ModelForm doesn't maintain core field arguments	stp2007 <stp2007@…>	nobody	"Using !ModelForm to generate a form class for cWilt. When overriding the default field type (for age in this example) field arguments 'verbose_name', 'help_text' and 'default' defined in the original model do not seem to be maintained and do not display correctly in the form. For example, help_text doesn't display at all and the label displayed is ""Age"" not ""Age - VName""
