Thanks for the debugging work, but, same question here as with the
other problem you observed in DataStore, I cannot really see how this
could happen (recordIds_ is always updated when rows are added or
removed to the model).
Are you using a standard model or one that you implemented yourself ?
If you are using a standard model, can you get me a stack trace when
this happens ? Or even better, a test case ?
If you are creating your own model, are you sure you call the
WAbstractItemModel::rowsAboutToBeInserted() and
WAbstractItemModel::rowsInserted() methods when inserting rows ?
