Do you actually need to store the value from A in all the Bs as well,
or do you only need to display the value from A in the editing
template for the Bs?
In the latter case, you can create a custom field plugin. You will
have access to the document node (through its JcrNodeModel) so you can
use the JCR API to look up node A. I've done this in a project a few
Hope this helps.
