| I went into the debugger and the dataset.update() method=20
is throwing the OleDb.DbException ...
What is curious is that the data is reflected in the=20
database and the same method=20
(ABCDService.LogABCDTransaction) when called from the=20
checkout.aspx instead of from the pipeline component does=20
not behave like this...
Even in the pipeline, this error is returned the SECOND=20
time around...
