ExtJS Code Completion / Intellisense in Netbeans

Here's how to get ExtJS code completion / intellisense working in Netbeans (6.9.1):

1. you need to reference extjs scripts locally, and not from a remote server
2. use the ext-all-debug-w-comments.js version
3. in netbeans, on the menu, go to tools -> options -> miscellaneous -> javascript tab -> and set the targeted browsers to the highest version numbers and set javascript version to 1.8
4. reference ext-all-debug-w-comments.js in your index file

<script src="ext/ext-all-debug-w-comments.js"></script>
