Question about itemfetchscope

[laurent Montel-2]

Hi,
In kmail I got item:


  Akonadi::ItemFetchJob *job = new Akonadi::ItemFetchJob( mTemplateFolder );
  job->fetchScope().fetchFullPayload();
  Akonadi::Item::List items;
  if ( job->exec() ) {
    items = job->items();
  }
  for ( int idx = 0; idx < items.count(); ++idx ) {
    qDebug()<<" items.at(idx).parentCollection() :"<<items.at( idx
).parentCollection();
    KMime::Message::Ptr msg = KMail::Util::message( items.at( idx ) );
    if ( msg ) {
      ....
   }
}

it works fine it's not a pb.
But when I test parentCollection it returns invalid parent !
I don't understand.
Why after an itemfetchjob parentcollection is invalid ?

What I am missing ?

Regards

You need to explicitly ask to fetch the parents too.

job->fetchScope().setAncestorRetrieval( ItemFetchScope::Parent ); for just
one parent collection, and ::All for all ancestors up to Collection::root.

That's @since 4.4  and I've needed to use it in most cases, so we should
probably make it the default...

Apparently it would be too expensive to be on all the time, so it's not
really a big deal.
