thilina01: opening a file from project tree after editing the file outside the netbeans

alex_sav: When i open an js file,then there aren't different colours to each code .So,net beans has a notificaition for unexpected error ,but i don't understand the problem.I have this version of net beans to another computer and it works correctly!

I was trying to reproduce the bug in NetBeans IDE 8.2 (Build 201609300101), but not able to simulate the issue.I followed the steps as mentioned in the link
http://statistics.netbeans.org/exceptions/detail.do?id=226117

Steps I followed are as under:

1. Imported the project https://gitlab.com/wissenstein/nb-js-editor-experiments.git in Netbeans.
2. Modified the JS files present in src\main\webapp\js directory (angular.js/default.js) from windows notepad.
3.Then opened those JS files in NetBeans IDE. It was able display the text in JS files properly without any exception.

Please let me know how can we simulate the issue in NetBeans IDE 8.2 or I missed some steps
