Hello everybody !
I've been working with the wicket-gae-template which provides a good
entry in gae, however I have a big issue :
I have 3 entities, Astre, Region and Colon ; Astre has a list of
Region ; Region has a list of Colon.
Astre {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent(mappedBy = "astre")
@Element(dependent = "true")
private List<Region> listeRegion = new ArrayList<Region>();
}
Region {
@Persistent
private Astre astre;
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent(mappedBy = "region", defaultFetchGroup="true")
@Element(dependent = "true")
private List<Colon> listeColons = new ArrayList<Colon>();
}
and Colon {
@Persistent
private Region region;
}
(with other fields)
so Astre is a root entity, Region is a child of Astre and Colon a
child of Region.
When I load an Astre, i can modify it, upload it. I can modify, say,
the name of the 1st region, and the name of its 1st colon ; when i
make a pmProvider.get().makePersistent(astre); the astre is updated
(I can see it with the dataviewer)
When I load a Region with a Key ID and modify its name, the
pmProvider.get().makePersistent(region); seems to do nothing. same for
Colon.
I have another root entity "UserData" with which i have also no
problem for updates.
Is there something I am missing about the updates of non-root
entities ?
