title: Spring integration delayer element
body: <p>I'm trying to configure my spring integration and want to use the  element, which basically sits between a retryFilter and a queue.</p>
  
  <p>All works fine if I go straight from the retryFilter to the queue, however, as soon as I put the delayer element in between them, the config file fails to be loaded (as happens when there is an error in it).</p>
  
  <p>Config for this section is as follows:</p>
  
  <pre><code> &lt;!-- Retry filter --&gt;
   &lt;filter
    input-channel="retryChannel"
    ref="retryFilter"
    method="doRetry" 
    output-channel="queueChannel" /&gt;
  
   &lt;channel id="delayChannel" /&gt;
  
   &lt;delayer input-channel="delayChannel" default-delay="10000" output-channel="queueChannel"/&gt;
  
   &lt;channel id="queueChannel"&gt;
    &lt;queue capacity="100" /&gt;
   &lt;/channel&gt;
  
      &lt;poller id="poller" default="true"&gt;
          &lt;interval-trigger interval="1000"/&gt;
      &lt;/poller&gt;
  </code></pre>
  
  <p>Any help greatly appreciated.</p>
