Did this now and the result wasn't really satisfactory. The HoursForm-code.py
contains:
## *!* ## Dabo Code ID: dDropdownList-dPage
def afterInit(self):
biz = self.Form.getBizobj("hours")
(names, pks) = biz.getClients()
self.Choices = names
self.Keys = pks
self.ValueMode = "Key"
self.PositionValue = 0
With this last statement I wouldn't expect any error message, because now a
valid list entry is explicitly selected. Right so far? But I get this:

In spite of this the control shows the first entry. But if I save the record
the clientfk is 0 and not the primary key of the first list entry (which is
1).
So I'm afraid this is worse than it was before. Value and PositionValue seem
to have got mixed up.
