Using Ext 2.0.2
I have a static tree that is loaded with json on page load. The tree is large, but not crazy huge - it has about 1,000 nodes total, the deepest ones being about 3 levels deep.
I've made an "Expand All" link on my page that simply calls
In Firefox, Chrome, and Opera the expansion is noticeably slow (maybe 2-3 sec), but tolerable.
But in IE6 and IE7 the expansion will never complete. In fact, taking a look at task manager shows that IE is taking up 50%+ CPU and chewing up memory. It does this until IE stops responding and needs to be killed. I assume it is ending up in a infinite loop somehow.
Anyone else experience this? I've tried other method of expanding it but don't see many other options in the API. A recursive cascade() seems just as slow and is probably what exandAllChildren() does internally anyway.
Any support would be appreciated. Thanks.
