Multiview, call view's function from others

Hi all,
I have 4 views in tabgroup, and a menu shown by all views. The menu's command handler is in separete file.

commandhandler.cpp:

TBool CommandHandler(TInt aCommand, CkeretAppUi* AppUi) {
  TBool res=ETrue;
  TFileName drvName;
  switch (aCommand) {
    case ECmd1:
      ...
    break;
    case ECmd2:
      ...
    break;
[...]
    default:
      res=EFalse;
    break;
  }
  return res;
}

I call it from view:

void CkeretView1::HandleCommandL(TInt aCommand)
    {
       switch (aCommand) {
         case EkeretSpecItem:
          iView->Search();
         break;
         default:
           if (!CommandHandler(aCommand,(CkeretAppUi*)AppUi())) {
             AppUi()->HandleCommandL(aCommand);
           }
         break;
       }
    }

My problem: I need to reach a function in view1 from all views. In commandhandler.cpp I tried this:

// shitch tabgroup
      AppUi->iTabGroup->SetActiveTabByIndex(1);
      AppUi->ActivateLocalViewL(TUid::Uid(EkeretView1Id));
// call function
      ((CkeretView1*)(AppUi->View(TUid::Uid(EkeretView1Id))))->iView->Search();

it crash before entering Search() function.

      ((CkeretView1*)(AppUi->View(TUid::Uid(EkeretView1Id))))->Search();

in view:
void CkeretView1::Search() {
  iView->Search();
}

This way it enters Search() function and crash inside!?!?

Any idea how can I call a view's (viewcontainer's) function from other views?

Thanks
