The golden rule of DropDownChoice is that the values in the list must be
the same as the property you are trying to set. In your case, if you
want basicDemographicInfo.gender to be set to "m" or "f", you must pass
the DropDownChoice the list [ "m", "f" ]. You'll then need a renderer
that produces the appropriate display value:
new ChoiceRender() {
public Object getDisplayValue(Object value) {
// here, value will be "m" or "f"
// look up and return "Male" or "Female" accordingly
}
}
You shouldn't care about the ID value. The default provided by
ChoiceRenderer should be fine.
