IllegalStateException: There is no database snapshot available...

Hi List,

I got frequent, random, hard-to-reproduce Exceptions if I add and
edit some larger amounts of detail objects im my Master-Detail-DisplayGroup
without saveChanges() in between. That all takes place in a cascaded
EditingContext. Objects are inserted via displayGroup.insertNewObjectAtIndex(0).
If I finally try so do a saveChanges() the Exception occurs.

I searched the lists and found only few posts, but they didnt really help. I try
to follow the 'EOF Commandments' and try to keep my EOModel clean. I got
this problem for a while now and looked around for solution in many different
ways, but nothing helped :(

Anyone got some hints what is causing this mess?

Many thanks in advance. Configuration details listed below.

Cheers
  Michael



Configuration of the DisplayGroup:

dgStammdaten = {
class = WODisplayGroup;
dataSource = {
class = EODetailDataSource;
detailKey = stammdatens;
masterClassDescription = StammdatenKonfig;
};
fetchesOnLoad = YES;
formatForLikeQualifier = "%@*";
numberOfObjectsPerBatch = 20;
selectsFirstObjectAfterFetch = NO;
sortOrdering = ({class = EOSortOrdering; key = name; selectorName = "compareAscending:"; });
};

and on component initialization: dgStammdaten.setMasterObject(stammdatenKonfig);


Configuration of Entity 'Stammdaten':
