I'm calling for the adjacencies of a triangle which I would expect to 
return a vector of entity handles of size 3, but it seems to be 
returning a vector of size 1.

To be specific I'm using:


virtual ErrorCode get_adjacencies(const Range &from_entities,
                                          const int to_dimension,
                                          const bool create_if_missing,
                                          std::vector<EntityHandle> &adj_entities,
                                          const int operation_type = Interface::INTERSECT);

and here's my call: get_adjacencies( tri, 1, 2, false, adj_tris);
