15602	Using get_readonly_fields and StackedInline/TabularInline admin objects doesn't allow creating new objects, immutible existing objects	bradwhittington	nobody	"I am using a pattern described [http://stackoverflow.com/questions/4343535/django-admin-make-a-field-read-only-when-modifying-obj-but-required-when-adding-n here], on a StackedInline admin class, AKA:

{{{
    def get_readonly_fields(self, request, obj = None):
        if obj:
            return self.readonly_fields+('text','author','private')
        return self.readonly_fields
}}}

But it seems to currently be broken (in 1.2.5), I get all fields repeated twice per object, and the add new object fields are all marked read-only, as if obj is always a non-None value. If I throw logging into that method (log.debug(obj==None)), I am seeing (in an example with one inline object already created):
