Problem with kDuplicateCmdBoss (IDCS3)

Hi,<br /><br />I have the following problem :<br /><br />After duplicated an item with kDuplicateCmdBoss, any action on my document cause crash of ID (not protective shutdown).<br />This is the "duplicate" function code:<br /><br />UIDList list(item);<br />UIDRef RefReturn = UIDRef::gNull;<br /><br />InterfacePtr<IHierarchy> hierarchy(item, UseDefaultIID());<br />ASSERT_AND_BREAK_IF_NIL(hierarchy);<br /><br />UIDRef parent(item.GetDataBase(), hierarchy->GetParentUID());<br /><br />InterfacePtr<ICommand> dupCmd(CmdUtils::CreateCommand(kDuplicateCmdBoss));<br />ASSERT_AND_BREAK_IF_NIL(dupCmd);<br /><br />InterfacePtr<ICopyCmdData> data(dupCmd, UseDefaultIID());<br />data->Set(dupCmd, &list, parent);<br />data->SetOffset(PMPoint(0,0));<br /><br />if (CmdUtils::ProcessCommand(dupCmd) == kSuccess) <br />{<br />     RefReturn = dupCmd->GetItemList()->GetRef(0);<br />}<br /><br />return RefReturn; <br /><br />What can i do ?<br />Thanks in advance.
