If you have action="#{bean.testAction}" and

public String testAction() {
  return null; // stay on same page
}

is this what you mean? I'm not at all sure what history.back has to do with anything.

Regards,
Brendan.

Can you post your code, it's not easy to follow without it.

login page:
<div id="header"></div>
<div id="footer"></div>
<div id="leftNav>
<ul>
<li>menu1</li>
<li>menu2<li>


</div>

<div id="centerPane">
</div>


when click on menu1 fetch myPage1.xhtml and place it in centerPane div...


now my centerPane div has

<div id="centerPane">
<div id="status" ></div>
<h:commandButton value="start" action="#{mybean.myMethod1}"actionListener="#{mybean.myMethod2}"/>


</div>

public String myMethod1(){
log.info("this line is printing from the navigateMe method: ");
return null;
}

how click on start commandButton displaying new page(i.e.myPage.xhtml)....[BUT THE VIEW SHOULD BE SAME WITH THE HEADER, FOOTER, LEFT AND CONTENT PANES...)

If you have action="#{managedBean.testAction}"
then you can use the code to return any page

public void testAction(){
 return "pageName";// without extenssion like return "login" for login.xhtml
}

However,

 return "pageName";// without extenssion like return "login" for login.xhtml  

Is not true. In JSF1, "pageName" would be the name of a Navigation rule. In JSF2, it can be the name of a navigation rule OR it can be a JSF context-relative URL. ".xhtml" is normally the extension of the resource, not of the URL, and resource paths and URLs are 2 different things that merely happen to resemble each other. You can, in fact, code

  return "pageName.jsf";

Although there's no practical benefit to doing so, since JSF already assumes that it's a JSF URL.

And of course, once again, coding a user-defined login is essentially telling hackers to invade your site and take over.
