inlines = [ProductImageInline, AttributeInline]

def get_formsets_with_inlines(self, request, obj=None):
    Yields formsets and the corresponding inlines.
    for inline in self.get_inline_instances(request, obj):
        if obj is None and isinstance(inline, tuple(self.inlines)):
        # Here problem when already create obj, and try change parent return
        #: Exception Value: ['ManagementForm data is missing or has been tampered with']
        elif obj.is_parent and isinstance(inline, ProductImageInline):
        yield inline.get_formset(request, obj), inline

Depending on whether the object is parent or not, will decide if to show some Inline,

not enough information to determine the cause of your problem, because you are give an example to your classes without theirs code
