A rewriting problem
I want to rewriting my page,code like this:
public class AutoLoginLinkTransformer implements PageRenderLinkTransformer {
@Inject
private RequestGlobals requestGlobals;
@Inject
private MainLoginService loginService;
@Inject
private TypeCoercer typeCoercer;
private String usrid;
public PageRenderRequestParameters decodePageRenderRequest(Request
request) {
if (filter(request)) {
return new
PageRenderRequestParameters(Space.class.getSimpleName(),
new ArrayEventContext(typeCoercer,
new Object[] { usrid }),
false);
}
return null;
}
public Link transformPageRenderLink(Link defaultLink,
PageRenderRequestParameters parameters) {
return defaultLink;
}
I want to the page rewriting to page "Space" and it sucess to the space,but
the browser's url is not change,
how can I solve this problem? Or is there any interface replace the
"PageRenderLinkTransformer".
My target is to add a filter,if it can not pass the filter's validate, then
page skip to another page.Is there any another way? If can share the code
is best.
Any one can help me, thanks a lot.

If I understand correctly you want the URL in browser to change.
PageRenderLinkTransformer.decodePageRenderRequest() is used for cases where
you want to override the way tapestry decodes a URL. It might be because you
want to use a different URL pattern or you have a generic url that you want
to map to a tapestry page. So this is a decoding of URL NOT a
redirection(which results in a URL change in browser)
What you need is a filter at some level of Request Processing
http://tapestry.apache.org/request-processing.html
Typically it is HttpServletRequestFilter or ComponentRequestFilter or
ComponentEventRequestFilter. The decision you have to make is how much
information do you need from tapestry to perform filtering. The lesser you
need, the early you can exit from the request processing pipeline.

That's expected behavior. URL rewriting doesn't changes URLs in the
browser, but how they are treated by the framework. Example: receiving
/test.html but make Tapestry handle it as if /test was requested.

Write a ComponentRequestFilter and use the service
ComponentEventResultProcessor. Here's a similar example in the mailing
list:
