Hi Igor,
The code did not work with even though the component was enabled.
The equals and hashcode methods are implemented for the LabelValue.
But instead of using my own Model implementation and managing the dynamic
behaviour,
i added a PropertyModel to the RadioChoice, and now it works perfectly.
Here is the code, if someone should be interested:
public class QuestionPanel extends Panel {
private LabelValue selectedValue;
radioChoice = new RadioChoice("radioChoice", new PropertyModel(this,
"selectedValue"), yesNoList, new ChoiceRenderer("label",
"value")).setSuffix("");
...
selectedValue = getPreviouslyChoosenLabelValue();
...
}
Thanks for the response Igor...
Best Regards
Muro
