I need to enable/disable a DateField everytime a dropdownlist changes its value.
I'm trying to call myDateField.disable() method, but it isn't working.
I'm using version 3.2.1 and this method is listed in documentation (http://www.sencha.com/deploy/dev/doc...form.DateField).

According to the error message in Firebug, the Method doesn't exists (myDateField.disable is not a function).

As I'm new to ExtJS, can anyone help me with this?

Thanks a lot.
