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!
