Mesh is not subdivided when scattered over surface

[Onizuka]

Hi,

I've got a problem with the subdivision when scattering trees.
I want to scatter trees on a terrain wich is ok, but when scattered the tree bark is not subdivided; But when I render the original mesh of the tree without scatter it, it's been subdivided and displaced correctly.
The pink sphere gets normally subdivided even when scattered.

Does any one know the problem here please ?

Ok I'm sorry, I've found the problem I've think to it but I was short on time so made a quick post.
But the problem was just that the subdivision occurs on scattered objects only on the principal component, not on groups inside the component; the subdivided group needs to be explode if the component is scattered.
I just didn't see it on the first time because the pink spheres were subdivided when scattered even if they were grouped by two inside a component, so I still don't understand this part, but the problem is solved.
