New description:

 When trying to enumerate values in a particular property in the expression
 editor, an !MgNullPropertyValueException is thrown if any null values
 exist for that property.

 This makes it difficult to work with that that contains these values; the
 current workaround I'm using is FDO Toolbox, but this can be difficult
 when the data isn't local.

 It would be great if Maestro's implementation of the expression editor
 could be modified to suppress these exceptions or, preferably, insert NULL
 as one of the choices in the value picker.
