#31 OnPostError - daAbort

[Alexis]

When handling an exception with OnPostError event, we assign DataAction:=daAbort.
Doing this, posting aborts ok, and MDODataSet continues pointing to the same record (tested with DataSet.Fields[x].Value), but dbaware components (tried with DBGrid and DBEdit) show data from another record.
Is this an MDO issue? Perhaps another Lazarus unit?
Thanks

Environment:
Lazarus 0.9.31 SVN, fpc 2.4.4, Ubuntu 10.04. Firebird 2.0 super server
