Invalid relationship - spring-data-neo4j

Question

I've got a class Account like (in Groovy):
#NodeEntity
class Account {
#GraphId
Long id
String accountId
String firstname
String lastname
#Relationship(type = 'HAS_INVITED', direction = Relationship.INCOMING)
List<Account> invitations = []
String getName() {
if (firstname && lastname) {
return "$firstname ${lastname[0]}."
}
return email
}
#Override
int hashCode() {
if (id) {
return id.hashCode()
} else {
return 0
}
}
#Override
boolean equals(Object obj) {
if (obj.is(this)) {
return true
}
if (obj instanceof Account) {
return obj.id == id
}
return false
}
#Override
String toString() {
"$email"
}
}
In my database, I've created 2 accounts Chris and Bob. Bob has invited Chris like below.
To load accounts, I've written this repository:
interface AccountRepository extends GraphRepository<Account> {
Account findByAccountId(String id)
Account findByEmail(String email)
}
Now, my problem: when I load the Chris account I get Bob as invited (it's ok). But, I've got Chris as invited for Bob and I don't understand why.
For me, I should have one invitation for Chris but 0 for Bob.

Any existing setter for INCOMING relationships must be annotated to avoid ambiguity during mapping. This is specified in the documentation:
The direction attribute on a #Relationship defaults to OUTGOING. Any fields or methods backed by an INCOMING relationship must be explicitly annotated with an INCOMING direction.
