When admin clicks the ‘Go to App’ on edit fan page, I am expecting the edit URL to invoke thru a POST along with a signed_request; instead the URL is getting called thru a GET with a ?fb_page_id=nnnnnn argument (where nnnnn is the pageId). No signed_request is received. I have filed this bug with Facebook (probably should be a key security enhancement, if this is not implemented yet)
Am I missing something, has anybody managed to get the signed_request on the invocation of Edit Tab URL ?
Btw, I have already managed to get the Page Tab URL to work and process the invocation that comes thru as a POST and a signed_request. All that is working fine, just looking for the Edit Tab URL.
Aha! Looks like someone recently entered this as a bug.

You should go there and me-too the bug so Facebook can send it higher up in their triage!
