Urgent Namespace Extension Issue

[WLM]

Hi,

My namespace extension has 5 sub folders. Once I switch from the root
to any sub folder, the content of that sub folder is displayed
properly. But then I switch to different sub-folder, the view never
gets refreshed. I debug the namespace extension and the
CreateViewObject never been called when I switching from one
sub-folder to another sub-folder. Looks like the Explorer thinking I
only have 1 sub folder instead of 5 sub folders.Anybody can help me on
this issue?

TIA
