opengraph - Publish custom facebook action on timeline as a Page -

i have created custom object , custom action open graph, , have been approved facebook. able publish custom action user, not page.

the steps follow are:

1. the user authorize app via login dialog, granting publish_actions permission
2. i exchange short-lived user_access_token long-lived one.
3. i fetch https://graph.facebook.com/me/accounts?access_token=... , page_access_token
4. i try publish custom action on page timeline on behalf of page, without success, getting enigmatic oauthexception message "an unknown error has occurred."

the auth dialog correctly asking permissions, , posting same custom action on user wall on behalf of user works properly.

is bug or missing something? managed publish custom action page?

i don’t think can undertake actions page – actions ment undertaken real people …
