Thank you for answer Pete

So you think that loading data from database should be done inside action method (here doSomething)?

What about first page load, where no action was fired?

first page load - getData
action load - getData, action, getData

For information - this is event scoped seam component and data are loaded from database. Such loaded data depends on your action, if no action, than load default data.

So here is code:

  | @Name("event")
  | @Scope(EVENT)
  | public class Event {
  |    List<Item> data = null;
  |    getData ... return data;
  |    setData ... this.data = data;
  | 
  |    doSomething() {
  |      if(linkParameter == null)
  |         loadDefaultDataFromDatabase();
  |      else
  |         loadDataFromDatabase(linkParameter);
  |    }
  | ...
  | 

so if you access page for first time, null data are returned, that is why i thought that loading data must be inside getters methods
