Here there is the snippet of code that I use to save my object:
...
private AtomicReference<DataContext> context = new
AtomicReference<DataContext>(config.getDomain("PacketDomain").createDataContext());
private <E> void CommitObjects(Class<E> objClass){
synchronized(context){
try{
context.get().commitChanges();
} catch(ValidationException e){
log.warn("Validation failed. " +
objClass.getName() +" discarded\n");
e.printStackTrace();
try{
context.get().rollbackChanges();
} catch(Exception e1){
e1.printStackTrace();
}
} catch(Exception e){
e.printStackTrace();
try{
context.get().rollbackChanges();
} catch(Exception e1){
e1.printStackTrace();
}
}
log.debug("Registered Count:
"+context.get().getObjectStore().registeredObjectsCount());
log.debug("New Count: "+
context.get().newObjects().size());
log.debug("Delete Count: "+
context.get().deletedObjects().size());
log.debug("Modify Count: "+
context.get().modifiedObjects().size());
log.debug("Cache Size:
"+context.get().getQueryCache().size());
context.get().getObjectStore().getDataRowCache().clear();
context.get().getQueryCache().clear();
}
}
Moreover, as you can see, I tried to add a synchronization on context in the
method that commit objects: the result has been a NullPointerException in
DataObjectUtils.java, line 114:
ObjectId id = dataObject.getObjectId();
if (!id.isTemporary()) {
return id.getIdSnapshot();
}
on "id" object.
Is there any other clues that may I provide?
Thank you very much
Best
