I am using the most recent versions of Drupal (7.14), Views (3.3) and the Entity reference module (1.0 rc3).
I have three content types. The first of them (parent) contains a node reference field to the second (child), which has a node reference to the third (grandchild). Each of these reference fields have unlimited values.
I have set up a block view, with relationships for both node reference fields, and have defined a contextual filter for the parent node id.
This is what I want to display in the parent node, each with summaries and a few other fields from the referenced nodes:
Child 1
Grandchild 1
Grandchild 2
Grandchild 3
Child 2
Grandchild 4
Grandchild 5
With displaying an unformatted list of fields, I get the following result (aggregation doesn't help at all):
Child 1
Grandchild 1
Child 1
Grandchild 2
Child 1
Grandchild 3
Child 2
Grandchild 4
Child 2
Grandchild 5
Any suggestions for how I can get the display that I want?
