-------------------------------

             Summary: Ignore missing Page in StatelessForm#process()
                 Key: WICKET-5158
                 URL: https://issues.apache.org/jira/browse/WICKET-5158
             Project: Wicket
          Issue Type: Improvement
          Components: wicket
    Affects Versions: 6.7.0
            Reporter: bernard
            Priority: Minor


I use StatelessForm because I want the page to be stateless with it in most cases but in other cases the page should become stateful.

A StateLessForm with multiple buttons replaces its parent panel at the end of the button's onSubmit().

After onSubmit(), StateLessForm#process() calls getPage() with the result of a RuntimeException "No Page found for component".

Martin Grigorov suggested to use #findPage() instead of #getPage()

Looking at StatelessForm#process(), I guess that a null check of the result of #findPage() may be required.

I don't understand the mechanics of "Remove the page parameters for all form component otherwise they get appended to action URL" so I can't assess the consequences of NOT doing this when a panel that contains the form replaces itself.

I guess it is ok to NOT execute that code in case where the page is gone.
