I didn't called the sessionContext.setRollbackOnly(). Simply I just call
the return statement.
tx = odmg.currentTransaction();
broker = ((NarrowTransaction)tx).getBroker();
//update the changed document
((NarrowTransaction)tx).markDirty(document);
List origBlock = document.getLogPondBlockList();
if(origBlock != null){
Iterator orig = origBlock.iterator();
while(orig.hasNext()){
((NarrowTransaction)tx).markDirty(orig.next());
}
}
Collection existed = broker.getCollectionByQuery(query);
LogPond dbLogPond = (LogPond)existed.iterator().next();
List dbBlock = dbLogPond.getLogPondBlockList();
if(dbBlock != null){
Iterator i = dbBlock.iterator();
while(i.hasNext()){
LogPondBlock dbLogPondBlock = (LogPondBlock)i.next();
if(document.getLogPondBlock(dbLogPondBlock) == null){
((NarrowTransaction)tx).markDelete(orig.next());
}else{
///error.. Can't delete this item
ON EXIST OF THIS METHOD, I FOUND THAT THE ABOVE MARK
DIRTY STILL TAKE EFFECT
return;
}
}
}

Stephen
