I have a Map that contains List of choices, my code is:
Map choicesMap = getChoicesMap();
Select select = new Select("mySelect", new PropertyModel(myModel,
"propertyName"));
IOptionRenderer renderer = new IOptionRenderer() {
public String getDisplayValue(Object selection) {
return ((Selection) selection).getName();
}
public IModel getModel(Object selection) {
return new Model(new Integer(((Selection) selection).getId()));
}
};
select.add(new SelectOptions("group1", new Model((Serializable)
choicesMap.get("group1")), renderer));
select.add(new SelectOptions("group2", new Model((Serializable)
choicesMap.get("group2")), renderer));
When myModel.getPropertyName() is null I get a WicketException:
09:50:07,679 ERROR [RequestCycle] Select
[3:step1Form:section4Border:mySelect] contains a null model object,
must be an object of type java.lang.Ob
ject or java.util.Collection (in case of multi-valued select element)
In other dropdown menu when model is null there is a entry like
'Choose one', they don't throw an exception!
Am I using your extension correctly?
Cheers,
