Problems with MeshVS

Hi all,

I've done my first steps with MeshVS and have some problems.
Here's what I do:

1) build a MeshVS
Handle(Im_MeshDataSource) aDS = new Im_MeshDataSource(theMesh);
Handle(MeshVS_Mesh) aMesh = new MeshVS_Mesh();
aMesh->SetDataSource(aDS);
aMesh->AddBuilder(new MeshVS_MeshPrsBuilder(aMesh.operator->()), Standard_True);

aMesh->SetDisplayMode( MeshVS_DMF_Shading );
aMesh->SetColor(Quantity_NOC_AZURE);
m_pAISContext->Display(aMesh);
m_pAISContext->Deactivate(aMesh);
if (m_pAISContext->HasOpenedContext())
m_pAISContext->CloseLocalContext();
m_pAISContext->Redisplay( aMesh );

2) for changing the display style (for AIS_InteractiveObject):
Handle(AIS_InteractiveContext) theContext = m_canvas->GetAISContext();
m_canvas->GetClientSize(&width, &height);
m_canvas->GetDocument()->GetAISContext()->Select (0,0,width,height,m_canvas->m_View);

for(theContext->InitCurrent(); theContext->MoreCurrent(); theContext->NextCurrent())
theContext->SetDisplayMode(theContext->Current(),0);

And here's the problem: after adding the mesh to my AIS_InteractiveContext it is always selected. But I cant change the display style because theContext has no current objects.

Anyone has an hint for me?

Greets,
