i'm trying to port an Ext 4 app to Touch 2 and I keep getting
Code:
Uncaught TypeError: object is not a function
in Chrome. This is really unhelpful to work out what I've done wrong.

Just now it was that I had layout: 'anchor' in a fieldset, but I've had this too for invalid xtypes.

Perhaps this could be caught earlier and echoed in the debug as wrong.
