I hope someone can give me a hand. I'm trying to do something similar, and
seemingly stumped.
I have a form that I want to have the user fill out, and then I just want to
email the completed form to someone on our team. So, I created subclasses
of form components that can be switched from "edit" to "view" mode, and that
works great. So, I submit the form, and swap them out to "view" mode so
that it is the exact same form, except instead of text fields and the like,
I then have labels that display the input, in an un-editable way.
Now, the problem: In the onSubmit() of my Button, I switch the fields over,
and then I would like to render the page to a String and email it, and then
render the page for the user.
I've tried the methods below, and both are failing - can someone please
help.
First, I tried JBQ's method, slightly modified since I'm not in a request
target. Maybe that's the problem. Maybe I need to specifically mount this
page to a request strategy as he does in the example. But, I'd rather be
able to accomplish this in the form itself.
final StringResponse emailResponse = new StringResponse();
final WebResponse originalResponse =
(WebResponse)RequestCycle.get().getResponse();
RequestCycle.get().setResponse(emailResponse);
RequestCycle.get().getRequestTarget().respond(RequestCycle.get());
// Here send the email instead of dumping it to stdout!
System.out.println(emailResponse.toString());
RequestCycle.get().setResponse(originalResponse);
RequestCycle.get().setRequestTarget(new BookmarkablePageRequestTarget(
Home.class));
I get this error (BTW - I'm on 1.2.6 with this app until we have an RC
release):
Caused by: java.lang.ClassCastException: wicket.response.StringResponse

I also tried using WicketTester in my onSubmit, and it failed:
WicketTester tester = new WicketTester();
tester.startPage(AdvertiseOnTHF.this);
String email = tester.getServletResponse().getDocument();
// Here send the email instead of dumping it to stdout!
System.out.println("EMAIL: " + email);
info("Your request has been sent.");
I can't do this because a lot of things in my app depend on getSession()
being my sub-class of WebSession, and getApp() being my sub-class of WebApp.
So, what to do? Any suggestions? Should I just mount this form
specifically to a request strategy and do it more like JBQ's example?
Thank you!

Yes there is a more direct way. I'm sorry I made an error, I
meant StringResponse, not StringRequestTarget. I spent a few
minutes writing the example, as this is a recurring question, here
it is:
http://svn.apache.org/viewvc/incubator/wicket/trunk/jdk-1.5/wicket-examples/src/main/java/org/apache/wicket/examples/staticpages/Application.java?revision=550248&view=markup
Look at the very bottom, where I'm using a custom
BookmarkablePageRequestTarget:
new BookmarkablePageRequestTarget(Page.class, params) {
/**
* @see
org.apache.wicket.request.target.component.BookmarkablePageRequestTarget#respond
(org.apache.wicket.RequestCycle)
*/
@Override
public void respond(RequestCycle requestCycle)
{
if (requestParams.getString("email") != null) {
final StringResponse emailResponse = new
StringResponse();
final WebResponse originalResponse =
(WebResponse)RequestCycle.get().getResponse();
RequestCycle.get().setResponse(emailResponse);
super.respond(requestCycle);
// Here send the email instead of dumping it to
stdout!
System.out.println(emailResponse.toString());
RequestCycle.get().setResponse(originalResponse);
RequestCycle.get().setRequestTarget(new
BookmarkablePageRequestTarget(Sent.class));
} else {
super.respond(requestCycle);
}
}
};
The example can be found in latest wicket examples in the
"staticpages" demo.
