Parameterized derived types with pointers to same type as components

Basically I have a derived type that represents a cell and I wanted it to have pointers to its neighbours. This is the data structure I would like to have:

module XYZ
...
    type pointerToCellContainer
        type( cellType ), pointer :: p
    end type pointerToCellContainer
...
    type cellType(nDOFs, nEQs)
        integer(itp), len :: nDOFs
        integer(isp), len :: nEQs
        ...
        type( pointerToCellContainer ), dimension(2) :: nb
        ...
    contains
        ...
    end type cellType
...
end module XYZ

While the module compiles fine when i try to atribute a cell to the pointer in the main program the compiler returns the error

main.f90(130): error #6795: The target must be of the same type and kind type parameters as the pointer.   [P]
        mesh%cellList(cID)%nb(1)%p => mesh%cellList(cID-1)
---------------------------------^
main.f90(131): error #6795: The target must be of the same type and kind type parameters as the pointer.   [P]
        mesh%cellList(cID)%nb(2)%p => mesh%cellList(cID+1)
---------------------------------^

My main doubt is if I'm actually trying to do something not allowed by the 2008 standard or if it's just a syntax problem. I'm doing this code to teach myself some features that I never got to use in production code (mainly parameterized derived types, submodules and other OO features) so workarounds and alternative design solution are also welcome.
