Hi
I've just run into this, code never reaches onUpdate of the behavior:
Java:
AjaxFormComponentUpdatingBehavior ajaxFormComponentUpdatingBehavior = new
AjaxFormComponentUpdatingBehavior(
"onchange") {
@Override
protected void onUpdate(AjaxRequestTarget ajaxRequestTarget) {
if (displayItemModel.getObject().getTakeDataFromCallCenterTo()
.equalsIgnoreCase("medium")) {
mediumTextField.setEnabled(false);
ajaxRequestTarget.add(mediumTextField);
}
}
};
DropDownChoice<String> radioChoice = new DropDownChoice<String>(
"TakeDataFromCallCenterTo", SITE);
radioChoice.add(ajaxFormComponentUpdatingBehavior);
html:
<select wicket:id="TakeDataFromCallCenterTo"
class="TakeDataFromCallCenterTo">
<input type="radio">none</input>
<input type="radio">high</input>
</select>
