Hi,
sorry, IPageRequestHandler#getPage() is new in Wicket 9.x:
https://github.com/apache/wicket/blob/0c747f494d0dacc0255a2162bee559c57719f0fb/wicket-core/src/main/java/org/apache/wicket/core/request/handler/IPageRequestHandler.java#L67
You can copy that method.
Have fun

Non-static method 'getPage()' cannot be referenced from a static context.

Hi,
instead of worrying about exceptions in your #onSubmit() and always
wrapping your code in catch-try, you can just use a general exception
handler:
getRequestCycleListeners().add(new IRequestCycleListener()
{
@Override
public IRequestHandler onException(RequestCycle cycle,
Exception ex)
{
MyCustomValidationException validation =
Exceptions.findCause(ex, MyCustomValidationException.class);
if (validation != null) {
Page page =
IPageRequestHandler.getPage(cycle.getActiveRequestHandler())
if (page != null) {
// add error messages ...
page.error(page.getString(validation.getCode()));
return new RenderPageRequestHandler(page);
}
}
return null;
}
});
Hope this helps

thanks again for answering my questions.
can you send me some examples of this concept?
(IRequestCycleListener#onException())
just I want to know more about that.

Hi,
you could use a FormValidator.
Or let your onSubmit() (or any code it forwards to) throw exceptions and
register an IRequestCycleListener#onException() to handle exceptions
during form submit.

I want to add form data to the database.
so it's not good to loading data for every input and checks from the
database.
I am using validation and when everything is ok then I connect to the
database for better performance :).
one Idea is to call the onError method into the onSubmit method. but I
want
to know is a better way to handle this situation?

Maybe it would be better to perform checks during validation ?

Hello
How can I pass an error in an onSubmit method?
I have some errors that can detect in the onSubmit method.
I throw exceptions at end of the onSubmit method.
In the catch block, I call the error method, but after that, I expect
to
don't go into the afterOnSubmit method, but he will go and I am
getting
the wrong response.
