How to add an URL-anchor to a redirect?

Hi T5 Users,

is it somehow possible to add an anchor-tag (example.com/#entry123) to a 
page redirect? I should control this inside the POJO, not in the 
template (there it's no problem).

The only way I found was by injecting the Link interface 
(org.apache.tapestry5.Link) but then I can't use the strong typed Java 
classes and I have to construct the URL manually.

I have this scenario: A user adds something to a form, if everything is 
ok he will be redirected to the display-page (for example by returning 
the injected page by the onActionMethod) where he can see what he has 
posted. Then he should of course automatically jump to his post => anchor...

Is there a solution?


Regards,
René

Hi Thaigo,

thanks for you answer!

That's it. I didn't know PageRenderLinkSource, so I couldn't create the 
link that easily.

For other users:
     @Inject
     private PageRenderLinkSource linkSource;

     private Object onActionFromAnchorLink() {
         long parameter = 123;
         Link link = 
linkSource.createPageRenderLinkWithContext(ExamplePageIndex.class, 
parameter);
         link.setAnchor("entry123");
         return link;
     }

Have a nice day!

Regards,
René

Use PageRenderLinkSource to create a Link to the page you want, add the  
query parameters, then return it in your event handler method.

Why not?
