title: What does <h:messages> do in JSF?
body: <p>I am learning JSF and came across this line:</p>
  
  <pre><code>&lt;h:messages layout="table"&gt;&lt;/h:messages&gt;
  </code></pre>
  
  <p>in a sample application ?</p>
  
  <p>Am not sure what does this line do? I get no error when removing the line from the code, and am able to run it and get the same output ?</p>
