We're having trouble making our form reset button work. It's defined
thusly:
AjaxButton button = new AjaxButton("reset-button");
...
<input type="button" value="Reset" wicket:id="reset-button" />
_____________________________________________
Here's our reset code, executed when the button is clicked. The main form
seems to re-render OK, but a
FormComponentPanel that is part of the form does not. I see a lot of
discussion on Wicket form resets on the Web, but most is several years
old. Is there an "officially" endorsed pattern or example for doing Ajax
form resets?
_____________________________________________
public void onReset(final AjaxRequestTarget target) {
final Component.IVisitor<FormComponent<?>> visitor = new
Component.IVisitor<FormComponent<?>>() {
@Override public Object component(final FormComponent<?>
formComponent) {
if (formComponent.getDefaultModel() != null) {
// Must have a model for the component
final Object currentValue =
formComponent.getDefaultModelObject(); // Save model value
formComponent.clearInput(); //
Clear out
formComponent.setDefaultModelObject(currentValue); // Add the value back
}
if (target != null) {
target.addComponent(formComponent);
}
return Component.IVisitor.CONTINUE_TRAVERSAL;
}
};
visitChildren(FormComponent.class, visitor);
}
