Re: readonly on trigger, etc.

Hi Erik,

Thanks for the clarifications. :)

Phew...yes, that's the bit I read. My recollection is that this was
added so that a processor could choose to remove any controls that the
user could not interact with, and get the same behaviour as a
processor that didn't remove them. So I think all it's saying is that
all events are dispatched when the xf:group is relevant (to the group
and its children) but when it becomes non-relevant, the group and any
contained controls will not receive events. (Although thinking about
it, it's much easier to say that the group still receives all events,
and the children receive none.)

Yes, I agree we need to clarify this. I think we should just say that
anything in the UI that is 'bound' to the model is a control, and have
done with it. Otherwise, what happens to Open Office controls, for
example?
