I was able to reproduce this bug as follows: 1) File -> New -> Synchronized C/C++ Project 2) Complete all required steps, including selecting a project type 3) Change "Connection Name" back to "Please select a connection" I think there are actually three bugs: 1) GitParticipant.getSyncConfigName doesn't check for null. 2) After selecting a connection, going back to "Please select a connection" does not invalidate the page. (The "Finish" button remains active after step 3.) 3) The UI lets the user select "Please select a connection". Fixing this would fix 2 as well.
