Linked entity references in a content type

I am unsure if this is possible in Drupal 7, but here is my problem: I have 3 content types, A, B and C.

B and C refer to A through a field field_A (entity reference).

C refer to B through a field field_B.

When creating/editing B, I want the user to select one node A1 of type A, and then, select some node of type B that refer to the node A1.

For example, let’s say I have these nodes:

- A1, A2 - B11, B12 referring to A1; B21, ..., B24 referring to A2

A user creates new content of type C, and selects A2: I want the user to be able to select items of type B among the list B21, …, B24.

I started to use an entity reference view to populate the list of B in C, but then was stuck because it is not possible (or I could not manage to do it) to refer to a field of the edited content type.

Thanks for any help!
