Hi everyone,
I'm quite new to extJS and currently evaluating it for a broder usage. But now I#m strungling with a browser specific problem. Hopefully it's a simple one...

Running the standard extJS 3.0 FeedViewer Sample in an IFrame (from within MS Sharepoint) under IE7 does not work properly: The javascript error is thrown when navigating:

'Ext.fly(...)' is Null or not an object.

Running this is a separate browser window does not cause a problem. In FF3.x this problem does not occur. Both pages a located in the same domain within our Intranet.

Anyone a clou ? Many thanks in advance...

Are there any general stability problem of extJS to be aware of before adapting it in a large scale (heterorgenious) enterprise context ?

how did you integrate EXTjs with Sharepoint? I am no sharepoint expert, so can you explain it in simple terms?

Using a Sharepoint webpart to point at another server hosting my Ext enabled website. FF has no issues... IE7 outside of sharepoint has no issues. IE7 and Sharepoint webpart (IFrame) produces javascript error 'Ext.fly(...)' is Null or not an object. on a button click.
