I have a class that keeps track of relationship data between two parties., so
part of it looks like:
Entity
| @Inheritance(strategy = InheritanceType.SINGLE_TABLE)
| public class PartyRelationship extends BasePersistentModel{
|
| @Temporal(TemporalType.DATE)
| private Date fromDate;
|
| @Temporal(TemporalType.DATE)
| private Date thruDate;
|
| @Lob
| private String comment;
|
| @ManyToOne
| private PartyRole relationshipTo;
|
| @ManyToOne
| private PartyRole relationshipFrom;
When I persist this, it goes to the database correctly. However when I
retrieve the relationshipFrom field by itself, it doesn't get retrieved. I've
looked at the code and can't see where it's mapping wrong.
I force the bi-directional relationships here:
| @Override
| public String persist() {
| PartyRole relationshipFrom =
getInstance().getRelationshipFrom();
| if( ! relationshipFrom.getInvolvedIn().contains(
getInstance())){
|
relationshipFrom.getInvolvedIn().add(getInstance());
| }
| PartyRole relationshipTo = getInstance().getRelationshipTo();
| if( ! relationshipTo.getInvolvedIn().contains( getInstance())){
|
relationshipTo.getInvolvedIn().add(getInstance());
| }
| return super.persist();
| }
And this works. Both the from and to are correct. When I pull the
relationship class itself, all the fields are correct. It's only the PartyRole
on the from side that doesn't get populated on retrieval, the to side works
just fine.
Any ideas on what I'm doing wrong?
