Adding it to a fieldset that contains the fields has no effect on the fields contained.
Adding it to a specific field only effects the label and not the input.
I can iterate the fields and set the css class explicitly (which is what I am currently doing to work around this issue), but my expected behavior is that an override of the disabledCls in the field config should effect both the label and input.
Neither config override has the expected effect on the field.
For future consideration, the primary use case that I am trying to handle here, is the ability to make a readOnly form panel. Except I don't want to make the fields grey (hence my override of the disabledCls). I merely want the panel to be uneditable.
When doing this with Ext. I use a staticTextField field class that uses a div instead of a input dom tag. I am considering adding that for touch, since it would allow for text wrapping on long strings.
I want to be able to use the same formpanel for a readonly version and an editable version.
