but does not dForm care of this in
def moveToRowNumber(self, rowNumber, dataSource=None):
""" Move the record pointer to the specified row."""
if isinstance(dataSource, dabo.biz.dBizobj):
bizobj = dataSource
else:
bizobj = self.getBizobj(dataSource)
if bizobj is None:
# Running in preview or some other non-live mode
return
return self._moveRecordPointer(bizobj.moveToRowNumber,
dataSource=bizobj,
rowNumber=rowNumber)
The form really wants the bizobj and not the 'DataSource'
