I am using the head build of code recommenders of above version.

When bringing up the view Codesearch Query and no matter whether I enter text or not and then press the green bar on the right with the tooltip "Submit the views code search query" I get a NPE……

The most convenient way to use code-search is by triggering it directly from code completion inside your active editor. I couldn't recreate your error ( i triggered a query from active java editor before). Did you trigger a code-search before using the button?

Anyways, Tobias will completely rework the code-search interface and views in the next weeks/months. 

Given that and the statement that the view is more a debug view than thought to be used by clients, I'd like to set this issue to WONT FIX and wait until Tobias comes up with a smarter UI in ~November.
