Sorry for the late reply, I have been away for a few days.
Not catching exceptions thrown from onUpdate is fine by me. However i
noticed in your code fragment onUpdate always gets called even after
an exception occurs. I don't think that should happen. Either onUpdate
or onError should be called after the updateModel but not both.
The following could work for me (not tested off course ;))
/**
*
* @see wicket.ajax.AjaxEventBehavior#onEvent(wicket.ajax.AjaxRequestTarget )
*/
protected final void onEvent(final AjaxRequestTarget target)
{
final FormComponent formComponent = getFormComponent();
boolean error =false;
try
{
formComponent.inputChanged();
formComponent.validate();
if (formComponent.hasErrorMessage())
{
formComponent.invalid ();
}
else
{
formComponent.valid();
formComponent.updateModel();
}
}
catch (RuntimeException e)
{
error=true;
onError(target, e);
}
if(!error)
onUpdate(target);
}
