CruiseControl git modificationset errors

I encountered some errors while configuring my phpUnderControl. One of the errors were the <git> <modificationset> not returning results, but the gitbootstrapper actually updated the git repository.

triggerHandler on live event bindings in jQuery

Toni Uebernickel
