Hi Goran,
I have a form with a radio group. Everithing works (page renders without
errors) but I can't get selected radio in forms onSubmit method.
model.getSomeRadioGroup() returns null.
It probably some logical error using the models. Does radioGroup have to
have its own model or something like that.
RadioGroup does need to have its own model and it also needs to be
included in the markup and it needs to wrap (be the parent) of the
specific radio's.
If your radio's are directly adjacent in the markup you might find the
RadioChoice class easier since you can just set 1 model and pass in a
list of the options.
Here is simplified example:
FORM:
public SomeForm(String id) {
super(id, new CompoundPropertyModel(new SomeModel()));
RadioGroup radioGroup = new RadioGroup("someRadioGroup");
add(radioGroup);
radioGroup.add(new Radio("radio1"));
radioGroup.add(new Radio("radio2"));
radioGroup.add(new Radio("radio3"));
}
You need to set a model value for each radio since wicket will do a
radioGroup.modelObject = selectedRadio.modelObject when the form is
submitted.
protected void onSubmit() {
super.onSubmit();
SomeModel model = (SomeModel) getModelObject();
System.out.println(model.getSomeRadioGroup()); // This returns null
System.out.println(model.getRadio1());// This returns null
System.out.println(model.getRadio2());// This returns null
System.out.println(model.getRadio3());// This returns null
}
FORMS MODEL:
public class EmailSettingsModel {
private String radio1;
private String radio2;
private String radio3;
private String someRadioGroup;
//... plus getters and setters
}
I would change this so that the options for the radio were and enumeration:
public enum EmailOptions { OPTION_1, OPTION_2, OPTION_3; }
then just use a regular Model to hold the values:
FORM:
public SomeForm(String id) {
super(id, new CompoundPropertyModel(new Model()));
RadioGroup radioGroup = new RadioGroup("someRadioGroup", new Model
(EmailOptions.OPTION_1);
add(radioGroup);
radioGroup.add(new EmailOptionRadio("radio1", new Model
(EmailOptions.OPTION_1)));
radioGroup.add(new EmailOptionRadio("radio2", new Model
(EmailOptions.OPTION_2)));
radioGroup.add(new EmailOptionRadio("radio3", new Model
(EmailOptions.OPTION_3)));
}
Where emailOptionRadio overrides the Component.getConverter(Class c) method to
return an IConverter for the EmailOptions enumeration like:
/* (non-Javadoc)
* @see org.apache.wicket.Component#getConverter(java.lang.Class)
*/
@Override
public IConverter getConverter(Class type) {
return new IConverter () {
/* (non-Javadoc)
* @see
org.apache.wicket.util.convert.IConverter#convertToObject(java.lang.String,
java.util.Locale)
*/
@Override
public Object convertToObject(String value, Locale
locale) {
if (value.equals("1")) {
return EmailOptions.OPTION_1;
}
else
if (value.equals("2")) {
return EmailOptions.OPTION_2;
}
if (value.equals("3")) {
return EmailOptions.OPTION_3;
}
else return null;
}
/* (non-Javadoc)
* @see
org.apache.wicket.util.convert.IConverter#convertToString(java.lang.Object,
java.util.Locale)
*/
@Override
public String convertToString(Object value, Locale
locale) {
EmailOptions opts = (EmailOptions)value;
if (opts == EmailOptions.OPTION_1)
return "1";
if (opts == EmailOptions.OPTION_2)
return "2";
if (opts == EmailOptions.OPTION_3)
return "3";
else return "";
}};
}
HTML:
<form wicket:id="form">
<input wicket:id="radio1" type="radio"/>
<input wicket:id="radio2" type="radio"/>
<input wicket:id="radio3" type="radio"/>
</form>
