namespace problem with Qt designer .ui file

[ttvo]

Hi all,

I'm using Qt 4.x with Visual Studio 2008 and Qt VS Integration. I created a test.ui designer file with corresponding test.h and test.cpp. The generated ui_test.h class has

namespace Ui {
    class testClass: public Ui_testClass {};
} // namespace Ui

namespace Ui {
    class testClass: public Ui_testClass {};
} // namespace Ui

To copy to clipboard, switch view to plain text mode 

Things are working fine. However, when I add my test.h and test.cpp to a namespace, the Qt VS integration can't automatically add the slot in those two classes when I double clicking on a widget on my test.ui file as I used to. It gave me a warning, "The project doesn't contain any class that uses this form!".

Is there a way to get around this? Thanks.
