Reproducible: Sometimes

Steps to Reproduce:
I opened some jsp/js files and changed tabs

Can you attach some of those files?  I haven't been able to reproduce this.

Comment 2 Nitin Dahyabhai

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

Nitin,

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