Ext Designer Team,
Thanks for another great product.
These bugs may have already been reported but:
(1) I noticed that I could not get my XML DataStore to load in the Designer until I blanked out the URL prefix in Preferences and included the complete URL in the url attribute of the store; and,
(2) Could not copy and paste to the URL attribute field of the store, had to type it in or at least modify the pasted URL in order for it to change.
