I am using JSF 1.2 and when I try to access my page I get this error: was not an instance of javax.faces.model.SelectItem. Type found: java.util.ArrayList.

I am creating this simple web page that has a drop down list, the data is coming from the database and should display but I get this error:


Here is the code from the jsf

                        <h:selectOneMenu value="#{clients.code1}">
                              <f:selectItem value="#{clients.selectItems}"></f:selectItem>
                  </h:selectOneMenu>

Here is the code from the backing bean:

            try{
                  System.out.println("Test in list");
                  if( selectItems == null ) {
                        selectItems = new ArrayList<SelectItem>();
                        SearchUtilDao sutil = new SearchUtilDao();
                        System.out.println("Test in list");
                        ResultSet rs = sutil.doSearchAll("Codes", con);
                        while(rs.next()){
                              Codes cd = new Codes();
                              cd.setCode(rs.getString("CODE"));
                              cd.setId(rs.getInt("CODEID"));
                              selectItems.add(new SelectItem(cd.getId(), cd.getCode()));
                              System.out.println("returned data: " + cd.getCode());
                        }
                  }

                  return selectItems;


I am using JSF 1.2 on tomcat 6.  Thank you
