19425	Inline Admin does not allow extra to be a property	dave@…	nobody	"this line


{{{
if not isinstance( cls.extra, int ):
}}}

in 

django.contrib.admin.validation

causes this to fail

{{{
class MyInline( admin.StackedInline ):
    @property
    def extra( self ):
        if condition:
            return 3
        else:
            self.max_num = 0
            return 0

}}}

and should be updated to this accordingly


{{{
if not isinstance( cls.extra, int ) and not isinstance( cls.extra, property ):
}}}
