#65 Date field in datagrid popup: dropdowns don't work

[Jean Jordaan]

When you have a datagrid containing date fields, dates are only registered if
you use the datepicker.

The difference between the two cases (dates are selected via the drop down
boxes, or via the datepicker), is that the datepicker submits e.g.
`period_from=2011-04-08+00%3A00+` and `period_to=2011-04-09+00%3A00+`, while
the dropdown submits only the component parameters (`period_from_year`,
`period_from_month`, etc.)

The fields in question are period_from and period_to -- the component parameters are ignored.

Where should this be fixed? Javascript to set the composite field upon submit?
Or serverside to notice the component fields?
