That error is raised when the number field is empty and Ext returns "". I think 
I'm
go  with your previous suggestion of returning java.lang.Number for the method
getValue() so that way null can be returned if the NumberField is empty. Will 
update
this issue when the change is made.

NumberField#getValue now returns java.lang.Number. null is returned for empty 
field
values. Note that in Ext 1.1 final, a value of 0 is returned as null. This will 
be
fixed in the bug fix release of Ext 1.1.

fyi the bug where a value of 0 is returned as null with NumberField has been 
fixed in
Ext 1.1.1

Please refer to the test case attached. It cause ClassCastException.

This was due to a bug introduced in Ext 1.1.1. See details here :
http://extjs.com/forum/showthread.php?t=15738

I've incorporated a workaround. Please test against a new build.

Thanks,
Sanjiv
