Hi Miguel, Unfortunately the original author osgManipulator doesn't pop on the mailing list too often so we are left trying to support it by reading the source code and the example. Last year I needn't to add some functionality to osgManipulator and took the opportunity to refactor it a bit to make it more flexible and simpler to use, I'm still doesn't under all the code though so still have to refer to the source code to work out what is going on.
What I would recommend is moving to a 2.9.x dev release or svn/trunk as these contain my updates to it. The updates remove the need for the Selection class completely, you can now just tell a dragger to move a users created and specified transform node. If you want support on older versions of osgManipulator I'm afraid I'll have to pass on this as I really only have a bit knowledge of the latest rev of osgManipulator. Robert.
