/**
 * A Popup drop-down Editor proxy that delegates operation to different implementations depending on whether
 * the cell should represent a list of values or single value. The need arose from incomplete dependent enumeration
 * definitions; e.g. Fact.field1=['A', 'B'] Fact.field2[field1=A]=['A1', 'A2']; where no dependent enumeration has
 * been defined for Fact.field2[field1=B]. In this scenario a TextBox for field2 should be shown when field1=B
