Control focus on input after a form feedback
Hi All,
I using wicket for my war application.
I use wickets validator and feedback to control form inputs and constraints.
so usefull . easy and amazing.
But:
I wish to set a focus on a wrong input field (or change color to red for ex)
after getting feedback error from wickets 'feedback'. but when this last one
(feedback) is invoked, I can't do anything. I have to focus manually (with
my pointer ) on the wrng field.
My question, how to control focus after feedback . or how to perfomr actions
afeter getting feedback.
Thanks a lot .
MA

It must be there. Check again.

In this case you need #onError().
Here just safe a transient reference to the first input field with an
error and use it in renderHead() to do what Sven suggested.

hI Sven Meier, Thanks for the trick , but that causes other issues.
firts: I use wicket version 1.4.16 and for some raison I can t upgrade to
1.5, and the methode renderHead(IHeaderResponse) is missing. I got only this
one renderHead(HtmlHeaderContainer container) . Note the given argument on
the seconde one (HtmlHeaderContainer and not (IHeaderResponse).
Seconde: my form has more than one input field. how to target to wrong
field. Can I do that by passing variables in PageParameters ? because if
feedback is invoked the onSubmit form methode will not be called, then I
can't passe variable in page parameters.
Any idea?
Thanks in advance
MA

Overwrite #renderHead(IHeaderResponse), check for the first component
with error message and add a little javascript:
response.renderOnLoadJavascript(String.format("document.getElementById('%s').focus()",
componentWithError.getMarkupId()));
Regards
Sven
