I created an app to post to pages the user chooses. How can I direct the message to a page Wall on behalf of the user? From my tests the post is sent, but the page can't see it and the page is not notified either.

I have OAuth extended Permissions of publish_stream, what else do I need to my post not being invisible?

I will try to clarify the problem in details:

1- I send a post to a Facebook page that is not mine, I'm just a normal user, via application that ask for publish_stream, read_stream permissions.

2- I verify the page logging as admin but no notification is delivered and I can't see the post on my Wall.

3-If I log as the sender user I can see the post on page Wall, it looks like the post is private and just the sender user can see It. If I try to recover the post via Graph API using the same user it returns false.

4- Only the users who has the app installed can see the post on page wall.
