-------------------------------
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.
