What could be the possible problem here? I really don't know.

This is a typical MSIE warning message whenever you request a X(HT)ML file which does not have a XSL stylesheet (which is basically like CSS for HTML).

That you're getting this on a Facelet page can only mean that the request URL did not match the URL pattern of the FacesServlet as definited in your webapp's web.xml. In other words, the FacesServlet has never got any chance to run, parse that Facelet file and do all the JSF works to generate a bunch of HTML so that the webbrowser has something sensible to work with.

There are 2 solutions for this problem:

Fix your request URL (the one in browser address bar) to match the URL pattern of the FacesServlet in web.xml. If it is for example <url-pattern>*.jsf</url-pattern>, then you need to replace .xhtml extension in URL by .jsf.
Change the URL pattern of your FacesServlet to <url-pattern>*.xhtml</url-pattern>. This way you do not need to worry about accidently seeing XHTML source anymore.

Please note that this all has nothing to do with "autosuggest problem". Work yourself through some basic JSF tutorials first. Our JSF wiki page has some good links.

Oh, before I forgot, the <center> element is deprecated since HTML4 in 1998. Do not use it. Use CSS margin: 0 auto;. Try to avoid reading tutorials/books older than 2 years.
