Hi,
I am working on JSF 2.0. I created one JSF page in my project and after deploying, when i opened my JSF page in the browser and by clicking view source code i observed that some extra code is added at the last. I did not understand why that code is added at the last after deploying.
For Example the below is one of my JSF pages source code
<!--

function clear_jsfForm()
{
clearFormHiddenParams_jsfForm('jsfForm');
}

function clearFormHiddenParams_jsfForm(currFormName)
{
var f = document.forms['jsfForm'];
f.elements['orgId'].value='';
f.elements['id'].value='';
f.elements['jsfForm:scroll_1'].value='';
f.elements['jsfForm:_idcl'].value='';
f.elements['tschid'].value='';
f.elements['jsfForm:_link_hidden_'].value='';
f.target='';
}

clearFormHiddenParams_jsfForm();
//--></script><input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="rO0ABXVyABNbTGphdmEubGFuZy5PYmplY3Q7kM5YnxBzKWwCAAB4cAAAAAN0AAEzcHQAGy9qc3AvZXhwL0pFWFBQSVYwMTAwVjAxLmpzcA==" /></form>

<!-- MYFACES JAVASCRIPT -->

can any one of you please tell me why this is happening!!!

Welcome to the JavaRanch, Abraham!

JSF is a general-purpose MVC framework system that binds View Templates and Models via vendor-supplier Controllers (the FacesServlet and the logic processors for the JSF tags).

The most common - although not the only - way of rendering the View is to convert it to HTML for use in a web browser. You are surprised that the client version of the View should contain meta-data and functionality that makes the Controller tasks easier?
 
It is sorta covered in the JavaRanch Style Guide.
