and it is synchronized and goes to <b>Immediate</b> mode if there is a client interested in receiving
notifications of changes in that view's data.</p>
<p>In other words, a view in <b>Default</b> mode is effectively in <b>Deferred</b> mode if no listeners registered to
be notified of its changes, and it is effectively in <b>Immediate</b> mode if there are such listeners
(for example, if there is GUI control bound to it).</p>

out of sync with its base data as long as there are no requests for this view's data.
The view is synchronized on demand, that is, it is synchronized when any request for its data arrives.</p>
