title: JSF - prependId not working?
body: <p>I'm trying to use prependId to shorten update commands.
  If I use qualified id's throughout, everything works fine.
  If I use prependId, the id cannot be found:</p>
  
  <pre><code>&lt;h:form id="form"&gt;
  &lt;p:dataTable id="table"&gt;
  //closing tags
  
  &lt;p:commandButton update=":form:table"&gt; //works
  
  
  
  &lt;h:form prependId="false"&gt;
  &lt;p:dataTable id="table"&gt;
  //closing tags
  
  &lt;p:commandButton update=":table"&gt; //works NOT!
  </code></pre>
  
  <p>Cannot find component with identifier ":table" in view.</p>
  
  <p>What am I doing wrong?</p>
