title: Post value using h:inputtext and a4j:support onkeyup
body: <p>I was originally posting a value in the h:inputText field with an a4j:commandButton but I had to change the commandButton to s:link because the commandButton is also triggering a pdf document to be exported, and I believe that with an ajax call, the doc is rendered on the browser instead. </p>
  
  <p>So now I am trying to post the value using h:inputText and a4j:support</p>
  
  <pre><code>&lt;h:inputText id="numberOfPatients" 
      value="#{printLabelsReqFormsAction.numberOfPatients}"&gt;
      &lt;a4j:support event="onkeyup" 
          action="#{printLabelsReqFormsAction.setNumberOfPatients(numberOfPatients)}"/&gt;
  &lt;/h:inputText&gt;
  </code></pre>
  
  <p>(sorry for the weird formatting..)</p>
  
  <p>My setNumberOfPatients(x) is getting called but I don't think I am passing the value correctly. How should I pass the value of the h:inputText field?</p>
