The form field for the recorder's report date did not remember the selected values when the user returned from the search results. Turns out the problems is a combination of
1) that field was populated by a fetchCol (rather then fetchPairs) invocation, because I needed only the one value and not the id and string
2) the array returned within recordersReportData invokes the select function, and that function requires array items to consist of two elements, and not one

So, as a workaround, in recordersReportDate() I now invoke fetchPairs and have it return the respite_rr_date field twice. Seems to work.

When I get a chance I'll see if there's some way to modify the select function so that it will work properly with an array of single-element items.
