问题
I have a mule flow with facebook connector(authorize); Before calling it I try to set some flow and session variables; When facebook authorize returns back to flow - these previously set variables do not present in flow and session anymore. Why is it so and how can I make my variables stay in message after facebook authorize?

This is a known issue: http://www.mulesoft.org/jira/browse/MULE-6847
Also the fact that http://www.mulesoft.org/jira/browse/CLDCONNECT-185 has been closed Unresolved with a Usage Issue status makes me wonder if doing anything but crafting an HTTP response in the flow that contains <facebook:authorize /> is actually discouraged.
You may want to upvote/watch/comment/re-open these issues if you think you have a strong case for it.
