The problem is that i have another controls (filter
query) on my page, that's why i can't hit DB only when clients==null
(filter values are not updated yet at this phase). Is there any way to get
phaseID in getter method of managed bean ?
Thanks

times
Hi,
There are several reasons why getters are called
more than once, for example, checking for value changes, rendering and
etc.
You can try lazy initialization to fetch only once
like;
private List clients;
public List getClients() {
if(clients
== null)
clients = fetchFromDB();
return
clients;
}
First call to the getter will hit
the db and set the clients list, other calls will just return the same list
and not hit the db.
