Echo Web Framework

No, there is not much information in the server message. The property is set using the usual routine:

  public void setURI( String uri )
  {
    setProperty( PROPERTY_URI, uri );
  }

You can view a test file here. At the very end of the file is the even listener with the replace and add code necessary to get the change required.

The response message after button click is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<cmsg xmlns="http://www.nextapp.com/products/echo/svrmsg/clientmessage.3.0">
<dir proc="CFocus">
<focus i="c_10"/>
</dir>
<dir proc="CSync">
<e i="c_10" t="action"/>
<p i="c_9" n="text">http://sptci.com/</p>
</dir>
</cmsg>
<?xml version="1.0" encoding="UTF-8"?>

<dir proc="CFocus">

</dir>
</group>
</smsg>

My client sync peer code for renderUpdate is as:

renderUpdate: function( update )
  {
    var property = update.getUpdatedProperty( echopoint.HttpPane.URI );
    if ( property )
    {
      this.component.set( echopoint.HttpPane.uri,  property.newValue );
      this._iframe.src = this.component.get( echopoint.HttpPane.URI );
    }
  },

I tried without checking the update.getUpdatedProperty also with same results. The equivalent test for client-side application works fine.
