project/series given to results2launchpad are overwritten by checkbox protocol deferred results

Good point, the behavior reported in this bug was actually intentional but it would make more sense for the target project and series to be overwritable from the command line.

The modified behavior is for the submission_prober script to use the project and series from the submission.xml file and for the resutls2launchpad tool to use those from the command line. The challenge was making it possible to use the same checkbox protocol for parsing the submission.xml file in both contexts. This was additionally a challenge because of the concept of DeferredProperty which proved to be an overly complex pattern to solve this problem and I'm sorry you had to wrap your brains around it. Instead, this has been replaced by a dispatcher capable of notifying listeners only when all events in a required set have been published. For example, only add devices when you have a system unit and a device otherwise, without a system unit, there's really no sense in attempting to add devices to nothing. Another advantage of this pattern is that parsing is done incrementally instead of parsing into an intermediate data structure before actually using the data.

The changes have been pushed to trunk and a new package is currently building, you will need to upgrade both python-lpresults and launchpad-results-tools to version 0.12. The production server will probably be updated by tomorrow. Please have a try and let me know if you can now specify a project and optional series on the command line.
