I want to replace "choose one" option in drop down choice with other String "successfully occured" and I dont want to show list item to set the default.
DropDownChoice<Person> customer = new DropDownChoice<Person>(
"customer", new PropertyModel<Person>(customermodel, "customer"),list, new ChoiceRenderer<Person>("name", "id"));
customer.nullValid
resource key when usingsetNullValid(true)
, which might be the one the OP is using ("successfully occured" seems like a valid null value) – Morell
