Get error "Trying to get property of non-object" while trying to insert form into page

[tnguyen14]

I used the built in form builder to add a form to a page, and got this error in the editor:

Notice: Trying to get property of non-object in /path/to/my/wordpress/directory/wp-includes/post-template.php on line 29

There is no built in form editor, only plugins. This looks like Jetpack. Try turning off all other plugins and seeing if it still happens. If it does, I would let them know: ​http://wordpress.org/support/plugin/jetpack

Thank you - you're right, it is a the jetpack plugin. I thought for a second it was a new thing that came with 3.5.

I deactivated all other plugins and the problem still persists. I would appreciate it if you could let someone know. Hopefully there will be a fix soon.

You should report it to them at the link above. Someone helping may have questions, etc., in which case it is best for you to be responding directly.

Ok thanks i just did. Sorry I misinterpreted for first comment as you would let them know, as if you were working on it or something.
Again, thanks for the guidance.
