Hi Igor,
I recently had the need to enhance your
AjaxFormComponentUpdatingBehavior to customize exception handling. Its
just a small modification but you might want to include it in the
wicket source. Here's the new OnEvent method and a new abstract method
to be called when an exception occurs.
Maurice
/**
*
* @see wicket.ajax.AjaxEventBehavior#onEvent(wicket.ajax.AjaxRequestTarget)
*/
protected final void onEvent(final AjaxRequestTarget target)
{
final FormComponent formComponent = getFormComponent();
formComponent.inputChanged();
formComponent.validate();
if (formComponent.hasErrorMessage())
{
formComponent.invalid();
onUpdate(target);
}
else
{
try
{
formComponent.valid();
formComponent.updateModel();
onUpdate(target);
}
catch(RuntimeException e)
{
onError(target, e);
}
}
}
/**
* Listener invoked when an exception occurred during the update of
the components model.
* @param target
*/
protected abstract void onError(AjaxRequestTarget target, Exception exception);
