    Default Hovering over disabled fields causes js error in IE 8

    Hovering over disabled fields causes js error in IE 8


    REQUIRED INFORMATION
    Ext version tested:
    • Ext 4.1
    Browser versions tested against:
    • IE8
    • Chrome 21
    Description:

    Hovering over disabled fields in a window will produce the following js error in IE8. I think it only happens when you hover off and on the text inside the component. Seems easiest to recreate with a combobox. Works fine in chrome.

    Code:
      'Ext.fly(...)' is null or not an object  ext-all.js, line 21 character 103901
    I'm able to create it regularly on different machines so hopefully you can too.

    Steps to reproduce the problem:
    • go to any page that has extjs enabled, for ex http://dev.sencha.com/deploy/ext-4.1...ow/layout.html
    • Paste this is IE's debug tools script tab
      Code:
      Ext.create('widget.window',{items: [{xtype: 'combo', value: 'someText', disabled: true}], autoShow: true})
    • Now hover your mouse over and off of "someText" in the disabled field. Within a few seconds you should get the error.
    The result that was expected:
    • no errors
    The result that occurs instead:
    • Ext.fly error
    Operating System:
    • Windows 7 64 bit
    • Server 2003

    Thanks for the report, this is a dupe of EXTJSIV-5176.
