BUG: #{redirect.returnToCapturedView} does not work with @Re

[fhh]

Hello!

I have a page action that calls a method that is protected by @Restrict and reads the parameters with @RequestParameters. If I access the page the login page comes up.

After a succesful login I am redirected to the original page thanks to #{redirect.returnToCapturedView} but then the protected method fails because of a NPE. The field that is annotated with @RequestParameter is not set.

Yes, only page parameters are captured. Use a page parameter instead of @RequestParameter.

Use a page parameter instead of @RequestParameter.

This will not work for me as I am using RESTful model where all data is passed in from another site.

Will this bug (?) be fixed in later releases? I guess the problem is that the request parameter map is immutable. Is that true? If so would it possible to add a fake request parameter map to which the capture view method will copy the real request parameters and that is also searched by interceptor?

And if this will not be fixed, what is the suggested workareound? Should I just add a wrapper class that moves the request parameter to the page parameters before calling the @Restrict method?

Thanks for any answers :-)

Why not? A page parameter is just an automatically applied request parameter, effectively the same as @RequestParameter on a property setter method.

Oops, sorry. I haven't read up on all the new features of seam. I thought you meant a page scoped parameter component.

Looking at the documentation now I think this should work for me. I will test and report back.

Thanks

Still no luck... This seems to be a bug! I switched to page params but still the parameter is nul,l after a returning to the captured view.

I ran this through the debugger and traced the bug down to org.jboss.seam.core.Pages.getViewRootValues(FacesContext facesContext). Things go wrong when retriving the page parameters:

 for ( Param pageParameter: page.getParameters() )
 {
 Object object = Contexts.getPageContext().get( pageParameter.getName() );
 if (object!=null)
 {
 parameters.put( pageParameter.getName(), object );
 }
 }

It loops correctly over my parameters but it fails to retrieve them: pageParamter.getName() delivers the correct string but Contexts.getPageContext().get() returned null. So nothing is ever put into the parameters map.

I tried to trace it any further but it was beyond my knowledge of JSF to get to the bottom of the problem. If you need more info please let me know.
