I have a form as shown above :

I would like to navigate it using 'tab' keys on the keyboard.but once the focus is on Major Release combo, when i press tab again. The focus shifts to 'Reset' button rather than to the Image Names field.

Image Names Field is a multiselect component.

ExtJS Version : 4.0
Facing this issue in IE,Mozilla and chrome.

Please let me know if there is a way to resolve this ?

Thanks n Regards,
