Why IShellView::SelectItem(pidl, SVSI_EDIT) can not work?

extension

Hi all,
I write a shell-extension for Win7. First I crate my-own folder under "MyCompute", then show subfolders in it. But I find a strange thing.
My shell extension supports to "rename" the subfolders. I call IShellView::SelectItem(pidl, SVSI_EDIT) to set the folder state to editable. It works well if i show the sub-folders with "Large icon", "Medium icon" "List"...
But when I show all the subfolders in "Details", the "rename" function can not work.
I trace the return value for IShellView::SelectItem(pidl, SVSI_EDIT), it is S_OK.
And I am sure the pidl is correct.
Can anyone help me? Thanks a lot.
