Hi, I'm thinking of migrating my xforms to orbeon, so I've been
following this list to see what issues I might be facing, but quite
frankly, this one confuses me unless I just don't get the picture--and
it is an important issue for me.

In mozilla, when you have a textarea bound to a node and you make
changes to that textarea the node is instantaneously updated. For
example, if you put an xf:output next to your xf:textarea, both bound to
the same node, you can see the changes to the output as you type if you
have the textarea incremental attribute set to "true", and even if not,
you can see an immediate update when you click anywhere outside the
textarea and the instance gets updated (refreshed?).

Is this not the case in Orbeon? This is important to me because I have
an entire bulletin board application built on this very concept.

Or if you are talking about a different use case, could you describe it
more from the user's point of view? Are you talking about updating the
instance from somewhere else in the form besides the textarea? like an
xforms-select or something and you want the textarea to reflect that
update? Is this not automatic?

This is really important to my application and my decision to migrate so
any clarification would be appreciated.
