Well, thank you Litty but I think there is still something missing to deal with. So I wrote a sample application and I'll send it to you at you gmail account (Sorry, I don't know how to attach a file here). Please review it .. and to be more clear again: this is what I don't know how to do.
You will find that I have two divs on the home page (RPCServics.html): (1) menu div and (2) content div. In onModuleLoad() method I create two links <a href='home'>Home</a> and <a href='about'>About Us</a>. What I need exactly is when the user clicks "Home" link, then the "content" div will hold the HomePanel (it's a class you could find in com.ePediaSy.client.panels package), and when he clicks "About Us" link the content panel should hold the AboutPanel. C'est tout! et merci beaucoup. I'm looking forward to hear from you. P.S. Please put the sample here in the thread if you know how to; I could not do it.
