Object for id could not be retrieved

I'm trying to find where in my model or code (which works otherwise properly) these errors are being thrown. 2009-10-01 12:41:01.281 WARNING - CORE: Object for id '[MendixIdentifier:: guid=-281466386776064 objectType=PipsAndSubbies.Job objectTypeHash=2 dataStoreCode=-1 objectStoreId=0]' couldn't be retrieved Unfortunately this message, unlike most, doesn't tell you at what point in a microflow or in Java it arose. Can someone tell me in what circumstances it can be thrown, and how best to go about finding the cause?

Judging by the guid (which is negative) I'd have to say that you're trying to do a retrieve on an object which has never been committed yet. Try committing some of your objects earlier on in your microflow/java actions and you should be able to find your bug relatively quickly.
