eclipse rcp - IInputSelectionProvider not considered by listeners of RCP SelectionService -


i have rcp application different views. views should interact each other through eclipse selectionservice. in view 1 have added selectionlistener with

getsite().getworkbenchwindow().getselectionservice().addselectionlistener(this.listener);

in view 2 have added selectionprovider 

getsite().setselectionprovider(this);

to working, implemented methods iinputselectionprovider in view 2. when run program, view 1s selection listener not invoked. after debugging, found out view 1 not added in list of listeners of view 2. in view 2 have method 

private listenerlist listenerslist = new listenerlist();  @override public void addselectionchangedlistener(iselectionchangedlistener iselectionchangedlistener) {   // todo auto-generated method stub   listenerslist.add(iselectionchangedlistener); }

which adds listeners iinputselectionprovider. question is: should call method. understanding eclipse selectionservice should 

getsite().getworkbenchwindow().getselectionservice().addselectionlistener(this.listener);

but doesn't work. have fill listenerlist myself? if yes, why have use selectionservice @ all? or have iterate through list of listeners calling other method , not using list @ all? because if inspect iselectionservice object

iselectionservice service = getsite().getworkbenchwindow().getselectionservice();

i see listeners. not part of listenerlist above.

the addselectionchangedlistener called every time view gets activated , removed when view not longer active. means: if view active , 'setseletion' called, views listening notified. if these views call 'setselection' nothing happens. no notification started.
