Hibernate datatable component

Question

Hi,
I'm building a component to display a datatable from a hibernate select statement. I want to have pagination and a sorting mechanism.
The problem now is that my component goes two times to the database. First time when he restores my view (lifecycle 1) and secondly when he creates my response (lifecycle 6).
I'm sure somebody was before me to create a component like this, but I can't find docs on the internet. Does somebody know where I can find a component like this. Note, I don't want to use spring, keep it clean only JSF and hibernate.
Thx in adv,
Pieter

hi;
actually you should not make a db connection in restoreview Phase, instead restore your datasource from the viewstate
in your components encoding phase you should make db queries.
please take look to the following code.
@Override
public Object saveState(FacesContext context) {
Object values[] = new Object[2];
values[0] = super.saveState(context);
values[1] = label;
return ((Object) (values));
@Override
public void restoreState(FacesContext context, Object state) {
Object values[] = (Object[])state;
super.restoreState(context, values[0]);
label = (String)values[1];
