Goto->File is broken

I'm running Demetra 5321 and for some reason the ctrl-shift-N functionality is very broken. For example if I just start typing something like "jibx" it will return nothing in the list even though there's a file called "jibx-binding.xml" in my classpath. However, if I type "*.xml" then move the cursor before the star and type "jibx", the file and a few related ones will properly appear in the list. I'm a ctrl-shift-n whore so this is a real pain in the ass for me. I tried disconnecting the source path in the module settings and then reassigning it to see if it would rebuild it's indexes but that didn't work. Any ideas on how I can fix this?
