[eclipselink-users] cascade=refresh does not work like expected

Hello,

 

[EL 2.1.1]

We’ve got three classes Vehicle, Tour and TourPosition. A Vehicle has zero, one or more Tours. A Tour has one none, one or more TourPositions (the stops)

 

So we declared

Class Vehicle {

  @OneToMany(cascade={CascadeType.MERGE, CascadeType.REFRESH, CascadeType.REMOVE}, fetch=FetchType.LAZY, mappedBy="leadTruck")

  @JoinFetch(value=JoinFetchType.OUTER) // Never remove this, or you will regret it - believe me you will.

  private List<Tour> tours = new ArrayList<Tour>(113);

  …

}

 

Class Tour {

  @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "tour")

  @JoinFetch(value=JoinFetchType.OUTER)

  private List<TourPosition> positions = new ArrayList<TourPosition> (113);

  …

}

 

When I call em.refresh (vehicle) I would have expected that the tours and their positions are also refreshed, but they are not. The only SQL-Statement that I get is:

SELECT DISTINCT t1.vehicle_id, t1.measure_id, t1.jdo_version, …, t0.tour_id, t0.filled_up, t0.tour_text, …

FROM vehicle t1

LEFT OUTER JOIN tour t0 ON (t0.vehicle_id = t1.vehicle_id)

WHERE (t1.vehicle_id = ?)

 

So, at least the TourPositions are _not_ refreshed.

 

Is this a known issue/feature/bug?

Do I miss anything?

If it’s a known bug, is it fixed in 2.1.2?

 

Kind Regards and happy christmas, Michael
