[CLOSED]'ref' config option not recognized, but is referenced in API docs
The 'ref' config in Ext3 is not recognized in Ext4. In the API docs for Ext.AbstractComponent, under 'itemId', it gives a reference to see 'ref' and 'id'. I know this is nit-picking, but I only bring it up to get an idea whether or not this is actually planned for Ext4. This it is a very handy feature, and I would be very disappointed to see go away!
