      Description

      Using auction 2.0 in a test I observed the following:

      Previously, we would POST a blocking request to listen for updates

      POST http://localhost:8080/auction/javax.faces.resource/listen.icepush.jsf

      and get a response once a second:

      <notified-pushids>apushId</notified-pushids>


      Then fetch the update:
      POST http://localhost:8080/auction/auction.jsf

      and the update would be something like:

      <?xml version='1.0' encoding='UTF-8'?>
      <partial-response><changes><update id="rpt1:0:otime"><![CDATA[<span id="rpt1:0:otime">7d 1:54:53</span>]]></update><update id="rpt1:1:otime"><![CDATA[<span id="rpt1:1:otime">3d 4:54:44</span>]]></update><update id="rpt1:2:otime"><![CDATA[<span id="rpt1:2:otime">2d 7:55:34</span>]]></update><update id="rpt1:3:otime"><![CDATA[<span id="rpt1:3:otime">7:54:49</span>]]></update><update id="javax.faces.ViewState"><![CDATA[4506655347714165083:6047748643060694507]]></update></changes></partial-response>


      This would occur once a second. Now, however, we're getting two updates per second. The first is similar to the above as the clock polls, but the second update seems to contain a change only to the ViewState key.


      POST http://localhost:8080/auction/javax.faces.resource/listen.icepush.jsf


      ?xml version='1.0' encoding='UTF-8'?>
      <partial-response><changes><update id="javax.faces.ViewState"><![CDATA[4506655347714165083:6047748643060694507]]></update></changes></partial-response>



      Comparing the javax.faces.ViewState field from both updates, they are seen to be equal, so the second update is entirely redundant.
      <![CDATA[4506655347714165083:6047748643060694507]]>

      <![CDATA[4506655347714165083:6047748643060694507]]>


      This means we're doing 2 pairs of requests every second.
