Hi,
Drop a af:autoSuggestBehavior from component pallet to the SOC component and bind it to a backing bean method as below
private List<SelectItem> items = new ArrayList<SelectItem>();
public List getSuggestions(String input) {
if (input!=null && input.length()>3) {
ViewObject vo = util.getViewObject("XYZ1Iterator");
vo.setNamedWhereClauseParam("bindx]Xyz", input);
vo.executeQuery();
System.out.println("Row count is " + vo.getRowCount());
// autoSuggestItemBeanList.clear();
RowSetIterator itr = vo.createRowSetIterator(null);
while (itr.hasNext()) {
Row row = itr.next();
items.add(new SelectItem(row.getAttribute("FirstName")));
return items;
If you don't want your db to be queried for each and every character, then create a bean and set each and every attribute value of that bean from the db after your page gets rendered. So each character hit from the keyboard will look into your bean rather than hitting the db.
