using namespace with VS integration

Is there a way to write a class with namespace that utilizes the .ui file generated from the Visual Studio Integration? Everything seems fine until I try to connect a signal from the widget by the contextual menu. It prompts a warning that says

"Warning!
The project doesn't contain any class which uses this form!"

Here is a code snip

Code:

---

namespace space
{
 
class A : public QMainWindow
{
	Q_OBJECT
 
public:
	A(QWidget *parent = 0, Qt::WFlags flags = 0);
	~A();
 
private:
	Ui::AClass ui;
};
 
}	// namespace space

---

The error goes away after I have removed the namespace. Is there a way to use the form in a namespace'd class?

Thanks a lot!
