title: JSF 2.0: Why does f:ajax send all the form fields and not only those marked with execute-attribute?
body: <p>Seems like I am having a bunch of JSF related questions these days... here it goes again: why does AJAX call declared with <code>f:ajax</code> post all the fields of the form and not only those declared with <code>execute</code>? This question <a href="http://forums.oracle.com/forums/thread.jspa?messageID=6498666" rel="noreferrer">was already asked</a> in the Sun forums, but as they are now closed I cannot reply there. The thread there is a stub with no real answer to this.</p>
  
  <p>What's the point of submitting all the form fields if I need to use only some of them?</p>
