We have the same kind of requirements for our app. We use the setEnabled
method of FormComponent to mark a field as disabled (setEnabled(false)),
then when it is rendered, it defaults to having the disabled attribute added
to the field. The only problem that we have noticed is that TextArea does
not work as we would like it when disabled because it becomes unscrollable,
instead we override the onDisabled() method of TextArea to set the readonly
attribute as well as a css style attribute ("color: GrayText;") to make it
appear disabled.
