Martin,
are you using the simple mapping (w/o AJ) or the advanced AspectJ mapping?
I assume the simple mapping:
There are several ways of persisting a RelationshipEntity()
* (template or repository).createRelationshipBetween()
* (template or repository).save(new Role(movie, actor, rolenName));
* node-entity with @Fetch @RelatedToVia SetRole roles=new HashSetRole();
actor = (template or repository).findOne(actorId); // or other loading
mechanisms
actor.roles.add(new Role(movie, actor, rolenName));
(template or repository).save(actor)
if you are not using the first approach, you have to provide a RelationshipType
for Role
* as part of the @RelationshipEntity(type=TYPE) annotation
* or as a @RelationshipType String type; field
We can also have a skype call if you want to clarify things.
HTH,
Michael

Hey,
after reading the docs and looking at the examples, I give up trying to
find a solution for myself. The problem is the following: How are
@RelationshipEntity classes persistet? I have the same stucture as in
the Movies Example: the classes Actor -- Role -- Movie. When adding a
new Role to an Actor and saving the Actor Entity using the
ActorRepository, the new edges are not persisted in the database. Do I
have to persist the Role Entities manually? If yes, what Repository
shall I use for that?
this is part of my Actor class
@GraphId
private Long id;
// 1:n relation
@RelatedToVia
CollectionTMS_Rel OpTmRs;
// 1:1 relation to store the latest link ... this works and the
ede is persistet
private TMS OpTmRs_Latest;
this is part of my Role class
@GraphId
Long id;
@StartNode
WTUR wturInstance;
@EndNode
TMS tmsInstance;
long timestamp;
and finally this is the other end of the edge, my Movie class
@GraphId
private Long id;
@RelatedTo(type = TMS_REL, direction = INCOMING)
SetWTUR wturs;
@RelatedToVia(type = TMS_REL, direction = INCOMING)
IterableTMS_Rel tmsRels;
So, all single edges work perfectly, but the sets don't. Hope someone
can help me out with that
Greetings, Martin
