The same problem i have, you can have an eye on my questions aswell
Just Starting Help
Ok, I have been wrecking my brain trying to learn the basics. Every example I do I get a blank page. I'm using a mac and safari to view also my iPad. I can see the title in the webpage but comes up blank.
Without more information it's hard to know exactly what the problem is.
Personally I found that the "Getting Started…" tutorial was a good one to begin with, even if it doesn't answer every question we might have about working with Ext.js:
If nothing else, that tutorial set me up with a proper workspace and a working application which I've been tweaking and modifying. I hope this helps.
Hope this helps!
