Your "searchBean.getStartIndexDisplay()" is throwing an exception. Can
you provide the code for that function and the get/setSearchTerms
functions?

Thanks for the help. I've tried something similar

And I receive the following error
javax.servlet.ServletException: Cannot get value for expression
'#{searchBean.startIndexDisplay}'

(FacesServlet.java:152)

If I use this code in my "setter" to check if the param is available, I'm
able to get the value from the form below. Any ideas?
.
Object terms = FacesContext.getCurrentInstance
().getExternalContext().getRequestParameterMap().get("searchTerms");
if(terms != null){
this.searchTerms = terms.toString();
}
performSearch();
<form name="frmSearch" action=
"searchResults.jsf" method="get"

"searchTerms" type="text" value="Search"

I've been using EL (obviously since I have JSF pages), but I'm not sure how
to bind to bean values using simple HTTP named params.
