I've just downloaded WebStorm for use with EXT JS 4. I can get code completion working by using hte download option for EXT JS. However, this is for v3 and doesn't contain non-core classes. If I try to point to "ext-all-debug-w-comments.js" file from the EXT JS 4 installation I downloaded, WebStorm doesn't recognize the Ext object. Has anyone gotten this working?
