Re: getter called few times

[Cagatay Civici]

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.
