If I understood you correctly, I've done something like this to show a
different page depending on a url parameter. You should override the
newRequestCycleProcessor() method of your application class, and return a
different request target from the resolve method. Here I return a
bookmarkablepagerequesttarget which creates a new home page if a certain
parameter exists in the request:
@Override
protected IRequestCycleProcessor newRequestCycleProcessor() {
return new WebRequestCycleProcessor() {
@Override
public IRequestTarget resolve(RequestCycle cycle, RequestParameters
params) {
if (null !=
params.getParameters().get(ContentSearchPage.PARAM_SEARCH_KEY)) {
return new
BookmarkablePageRequestTarget(ContentSearchPage.class);
}
return super.resolve(cycle, params);
}
};
}

hi,
i'm integrating a wicket application with an online payment system
provided by a bank.
i have a wicket stateful page (ie shows visa / mastercard icons) which
links to the bank app's payment page. depending on the transaction,
the bank sends us back a result code in an encrypted http url
parameter, appended to the url of our wicket page.
String encrypted =
getWebRequestCycle().getWebRequest().getHttpServletRequest().getParameter("DATA");
according to the bank's response, i decide whether to show a "please
pay" or a "thank you" page with wicket variations.
the only problem i am having here is: the wicket page is cached, so no
matter what the result is, it will show the last seen version in the
pagemap - that is, it won't re-execute the page's java code.
i tried overriding headers
protected void setHeaders(WebResponse response) {
response.setHeader("Pragma", "no-cache");
response.setDateHeader("Expires",0);
response.setHeader("Cache-Control", "no-cache, max-age=0,
must-revalidate, no-store");
}
but none of these http headers are seen in the html output whatsoever.
i also tried implementing IMarkupCacheKeyProvider and returning null.
with no success so far.
what should i do to execute the page's code, no matter when it is called?
thanks,
francisco
