ListField and Keyfield properties have a string editor enabled rather than a combobox of the available fields from the ListSource assigned. Can you fix this?
Using Delphi 2007 and Ver: 0.8.2.316_Unstable Build 2007.05.21
This is not a bug of CnWizards, but a problem of Delphi2007. Delphi2007 does not register FieldName PropertyEditor for TDBLookupComboBox.ListField and KeyField, so they use CnWizards's string editor. You can disable CnWizards from start menu to verify this.
