How to keep content of view during switching views

[Hiero]

Hi.

I have 2 views and one container in each of them. Containers contains ListBox created dynamically. I'm switching between views in UI (class derived from CAknViewAppUi) like is it taking place in most of Symbian apps.

During switching I use DoActivateL and DoDeactivate functions in each of view classes. It looks like:

void CsymContainerView::DoActivateL(const TVwsViewId& /*aPrevViewId*/, TUid /*aCustomMessageId*/, const TDesC8& /*aCustomMessage*/)
{
	SetupStatusPaneL();
	
	if (iSymContainer == NULL)
	{
		iSymContainer = CreateContainerL();
		iSymContainer->SetMopParent( this);
		AppUi()->AddToStackL( *this, iSymContainer);
	}
	else
	{
		//AppUi()->AddToStackL( *this, iSymContainer);	
	}
}

void CsymContainerView::DoDeactivate()
{
	CleanupStatusPane();

	if (iSymContainer != NULL)
	{
		AppUi()->RemoveFromViewStack( *this, iSymContainer);
		delete iSymContainer;
		iSymContainer = NULL;
	}
}

It runs ok but, every I switch to another view and back, the content is reseted and this is correct.
If I uncommnent from DoActivateL():

//AppUi()->AddToStackL( *this, iSymContainer);

and remove from DoDeactivate():

delete iSymContainer;
iSymContainer = NULL;

I can switch from first view to second but when I switch back to first I still see freezed content of second view's constainer. The menubar is switched correct, key events are handled proper even during debugging i know that I am working on correct container from first view but I see from second...

What could be the problem? IMO it is connected to wrong refresh of ListBox implemented into view's containers.

Please give me any hint. Sory for my English :).

Heh, it was easy for you wizard, parallel threads in the same time :).
Nevertheless thank you, somebody could add that the second MakeVisible(ETrue) in DoDeactivate() should have converse parameter but it is easy to guess :).

Again thank you for help.
