There are demos available for versions 2 and 3 of the feed viewer component:
- v2: http://extjs.com/deploy/ext/examples...ed-viewer.html
- v3: http://extjs.com/deploy/dev/examples...ewer/view.html
The particular Feedburner feed I'm using ....
... works with version 2 but not 3.
I'm getting this error from feed-proxy.php:
Failed to Parse XML Document Reason: The element type "content:encoded" must be terminated by the matching end-tag " ". Line: 4 Column: 97
(the demo feedburner.com/ajaxian feed works fine on both)
Perhaps not checking for the closing bracket when replacing content:encoded might work?
