Maybe we should do something like this?

             context_or_page = data.get('context') or data.get('page')
-            if context_or_page and context_or_page.resource:
+            if (context_or_page and hasattr(context_or_page, 'resource')
+                and context_or_page.resource):
                 script_data['realm'] = context_or_page.resource.realm
                 script_data['id'] = context_or_page.resource.id

The patch looks good to me.

In 17198:

WikiAutoCompletePlugin: Avoid problems with SpamFilterPlugin where page is int.
(see #13439)

Thanks.

Checked, it's fine :-)

Thanks.
