For Sencha Touch it seems that triggering a Ext.Msg dialog from a callback for a Ext.Msg dialog causes a TypeError. Here's a test case: https://fiddle.sencha.com/fiddle/2l2

Touch version tested:
  • Touch 2.3 rev 1
Browser versions tested against:
  • Chrome 31.0.1650.63
DOCTYPE tested against:
  • When a callback from a Ext.Msg dialog triggers another Ext.Msg a TypeError occurs.
Steps to reproduce the problem:
  • In Sencha Touch, trigger an Ext.Msg.alert or Ext.Msg.prompt dialog
  • Set the dialog's callback to trigger another dialog
The result that was expected:
  • No TypeError would occur
The result that occurs instead:
  • A TypeError occurs
