I'm using entity beans with a date property:
@Column(name="edate", nullable=true) // uses java.util.Date
public Date getDate() { return date; }Problem is, that em.merge(entity) and em.find(entity) return different results: E.g:
2005-11-05 19:59:18,908 DEBUG [SocketServerInvokerThread-141.44.198.37-22:net.mdlug.lugmanager.server.EventBean:248]
- ###################merge:date=1131145200002
2005-11-05 19:59:18,917 DEBUG [SocketServerInvokerThread-141.44.198.37-22:net.mdlug.lugmanager.server.EventBean:253]
- ###################merge:date=1131145200002
2005-11-05 19:59:19,025 DEBUG [SocketServerInvokerThread-141.44.198.37-22:net.mdlug.lugmanager.server.EventBean:61]
- ###################em.find id=1 1131145200000
...
public Event merge(Event ec) {
if (log.isDebugEnabled()) {
log.debug("###################merge:date="
+ ((ec.getDate() != null) ? ec.getDate().getTime() : ""));
}
ec = em.merge(ec);
if (log.isDebugEnabled()) {
log.debug("###################merge:date="
+ ((ec.getDate() != null) ? ec.getDate().getTime() : ""));
}
return ec;
}
public Event getEvent(int id) {
Event e = em.find(Event.class, id);
if (log.isDebugEnabled() && e != null) {
log.debug("###################em.find id=" + id + " "
+ (e.getDate() == null ? "" : e.getDate().getTime()));
}
return e;
}So I guess this is a bug, since merge does not return the instance, the state has been merged too ...
