Reproducible: Sometimes

Steps to Reproduce:
I opened some jsp/js files and changed tabs
Comment 1 Nitin Dahyabhai CLA 2011-04-25 10:16:14 EDT 
Can you attach some of those files?  I haven't been able to reproduce this.
Comment 2 Nitin Dahyabhai CLA 2011-04-25 10:22:19 EDT 
Patric, was your JSP file in a WebContent folder, or at least somewhere designated as a JavaScript Source folder?
Comment 3 Patric Rufflar CLA 2011-04-28 06:48:03 EDT 
Nitin,

yes, all the js/jsp files have been located within the WebContent folder.
