How to identify facebook timeline element to post smt with Robot Framework

please can u help me to identify element ID or any other locator of timeline composer in facebook profile ?

I need this to use in Robot framework with selenium2library to post smt on my wall. I can log in to fb, navigate to profile, but I cant input text into timeline composer. I tried to use Click element before inserting text but no succes.

I am using "inspect element" in browsers/firebug add-on to identify elements. In this case unfortunatelly all locators I have tried giving errors like: "Element does not appeared in 5secs" or "Element must be user editable in order to clear it"

Sry for bothering but I am stacked for days now. Have a nice day
