Hi all,
I'm trying to update some TextFields in a FormComponentPanel when the user
selects a radio button from a RadioGroup.
Here is a fragment of my code that created Radio and RadioGroup objects:
add(nanp = new RadioGroup("nanp", new PropertyModel(this,
"phoneNumber.nanp")));
nanp.add(new Radio("nanpTrue", new Model(new
Boolean(true))).add(new AjaxEventBehavior("onchange") {
private static final long serialVersionUID =
-1406454064553153207L;
protected void onEvent(AjaxRequestTarget target) {
nanp.processInput();
target.addComponent(areaCode);
target.addComponent(countryDialingCode);
target.addComponent(routingDialingCode);
}
}));
nanp.add(new Radio("nanpFalse", new Model(new
Boolean(false))).add(new AjaxEventBehavior("onchange") {
private static final long serialVersionUID =
6475950784724594836L;
protected void onEvent(AjaxRequestTarget target) {
nanp.processInput();
target.addComponent(areaCode);
target.addComponent(countryDialingCode);
target.addComponent(routingDialingCode);
}
}));
The problem is that as soon as I click on one of the radio buttons, I get the
following exception:
WicketMessage: Can't convert null value to a primitive class: boolean for
setting it on [EMAIL PROTECTED]
Root cause:
org.apache.wicket.util.convert.ConversionException: Can't convert null value to

It looks like the model in RadioGroup is not updated when nanp.processInput()
is called. Any idea what I have done wrong?
By the way I'm using Wicket 1.3.2, JDK 1.5.0_15, Tomcat 5.5.26 and Firefox
2.0.0.12
Thanks,
