Whenever I navigate to Manage Study > Manage Visits > [edit] (any of the defined visits)
the values in the drop-down field for the Associated Datasets are not completely correct.

If the value has been set to "optional" or "required" it is displayed correctly. If
however the value has been set to "not_associated", the dropdown has the value for
"optional" selected. It is really a minor issue that just makes it easy to screw up
your visits if you are not careful.

All of my visits and datasets were defined manually in the GUI.
I an running the source from the trunk checked out on 3-12 and postgres 8.1.6.
