</script><p>Committed callbacks can be used in various scenarios:</p>
<ul><li>backup on commit;</li><li>database replication on commit;</li><li>client database synchronization.</li></ul>
<p>In our example we will create an
implementation for the last case. </p>
<p>When several clients are working
on the same objects it is very possible that the data will be outdated on some
of the clients. Before the commit-callbacks feature was introduced the solution
was to call <code>refresh</code> regularly to get object updates from the
server. With the commit-callback this process can be easily automated:</p>
<ul><li>objects are modified when the commit is done;</li><li>the successful commit triggers committed event on the clients;</li><li>committed event handler updates modified objects on the
clients.</li></ul>
<p>Let's open 2 clients, which will work with <a href="car.html" class="wikiLink">Car</a> objects,
and register committed event listeners for them.</p>

</span><p>You should see that client2 picked up the changes committed
from the client1 automatically due to the committed event handler.</p>
<p>Working with the committed event you should remember that
the listener is called in a separate thread, which needs to be synchronized
with the main application thread. This functionality is not implemented in the presented example, instead a simple thread Sleep(1000) method is used (WaitForCompletion method), which is not realiable at all. For a reliable execution use events and notifications from the committed callbacks.<br></p>
<p>It is a good practice to remove the committed event handlers
from the registry before shutting down the clients:</p>
