[beta1] FormDashboard has performance problem in IE8 when editing form.

In example http://dev.sencha.com/deploy/ext-4.0-beta1/examples/charts/FormDashboard.html

When you edit the value in the form one after another using tab, or use backspace it's too slow, likely way too slow in IE 6. We can see in the code some looping. The charts update should happen in idle time.

It's obvious that Sencha developer are not using a slow browser when they do stuff. I think they should attempt to find issue by using old browser on a slow computer. On the same idea, all the examples should trigger the new dependency loader (just load each js modules) to test the dependency declaration instead of loading the entire Ext JS library.

Hi, thanks for the report.

We already fixed some performance issues mainly due to the triggering of field events when loading a record into the form.

Thanks again for reporting this.
