When I click on Faces, it's empty, the import from iPhoto forget to import faces?
How did you imort from iPhoto? If you import using the Aperture Apllication menu
File -> Import -> iPh.oto Library
then all your Faces should be transferred from iPhoto.
Which of the two buttons in Aperture do you use to show your "Faces"? There is the "Faces" button in the Library panel and the "Faces" Button in the Toolbar. Both behave differently. The "Faces" button in the Library panel will reveal all faces, whereas the "Faces" Button in the Toolbar will only show the faces detected in the in the currently selected item (folder, project). So it may appear that faces are missing, even if they are included in the Aperture Library.
