Is it possible to edit wall posts?

Is it possible to edit wall posts? If so, how can I do this? Anyho开发者_运维技巧w, I'd like to replace a wall post with modified one. Wall posts often fail to read meta data which is provided by open graph elements when I post a link to Wall through my app.

This is not possible. According to the documentation:

Update

You cannot edit any of the fields in the status message object.

You can delete wall posts, like you can delete most objects. I do not if it possible to edit but you can repost your message.
