Here's how I handle page redirects...
1. Create a ComponentUtils service interface/implementation...
public interface ComponentUtils
{
public void redirectToPage( String pageName );
public void redirectToPage( IPage page );
}
public class ComponentUtilsImpl implements ComponentUtils
{
private IEngineService pageService;
public void redirectToPage( String pageName )
{
throw new RedirectException( pageService.getLink( false, pageName
).getURL() );
}
public void redirectToPage( IPage page )
{
redirectToPage( page.getPageName() );
}
public void setPageService( IEngineService pageService )
{
this.pageService = pageService;
}
}
2. In your hivemodule.xml file...
<service-point id="ComponentUtils"
interface="com.myco.web.service.ComponentUtils">
<invoke-factory>
<construct class="com.myco.web.service.impl.ComponentUtilsImpl">
<set-object property="pageService"
value="service:tapestry.services.Page"/>
</construct>
</invoke-factory>
</service-point>
3. Then, in your page/component, just inject the ComponentUtils service...
@InjectObject("service:myco.ComponentUtils")
public abstract ComponentUtils getComponentUtils();
4. Then use it!
public void someListenerMethod()
{
// Do something.
getComponentUtils().redirectToPage( "Home" );
}

Subject: Page rediraction problem
Hello , I'm trying to redirect users to the Home page when they are not
in role, but this doesn't happen and I don't kwno why, since the
debugger checks correctly, so it must be my code!
here it is what I'm trying to execute.
public void renderPage(IMarkupWriter writer, IRequestCycle cycle) {
JFlyPrincipal principal = getPrincipal();
if ( (principal == null) ||
(!principal.isUserInRole(getRoles())) ) {
cycle.activate("Home");
}
super.renderPage(writer, cycle);
}
Could someone help me please ?
Regards,
kiuma

Thank you it perfectly worked. But I wonder why to throw an exception to
go to another page (yes in my own case it was right to throw an exc.).
For example if I change user data, after post I would like to see his
card, why should I use an exception to go to that page, since it's not a
real exception?
