Hello,
the main problem is not the info-message.
When I call info("bla") in thze constructor, then the message is displayed.
I think the main problem is that the method getModelObject() (see method isChoiceAvailable())provides null, but it should not be null!
Here again my code:
The DropDownChoice initialized in the Page-Constructor:
XXXDropDownChoice dropDownChoice = new XXXDropDownChoice(
"xxx", listModel, new ChoiceRenderer("name",
"id"), false);
dropDownChoice.add(new XXXChoiceValidator());
form.add(dropDownChoice);
if (!dropDownChoice.isChoiceAvailable()){
getFeedbackMessages().info(dropDownChoice ,"An info text!");
}
The method isChoiceAvailable() in my XXXDropDownChoice is implemented using the model and the choices:
public boolean isChoiceAvailable(){
List baseChoicesList = super.getChoices();
Object choiceObject = getModelObject();
return baseChoicesList.contains(choiceObject);
}
Daniel
