   [5.1.0 NIGHTLY December 6] Problem with data binding and combo box

   
   
   
   

   
   

   I found a problem with data binding and a combo box. To demonstrate the problem I created this fiddle.

   Steps to reproduce the error:
   
   1. Select a task in the grid
   
   2. Click the "Edit" button
   
   3. Window opens but combo box is not populated with a value.

   
   

   This works fine with all the extjs 5 nightly releases until (and including) December 5.
   
   If I use a release after this date (include the 5.1 release) it no longer works and extjs prints this error message

   
   

   
   

   Code:

   
   

   
   Uncaught TypeError: undefined is not a function
   Ext.define.doSetValue
   Ext.define.setValue
   Ext.define.privates.onBindNotify 
   Ext.define.privates.notify
   Ext.define.privates.react 
   Ext.define.notify 
   Ext.define.onTick
