Retrieve ActivationRequestParameters in custom PageResponseRenderer

  Hey folks,

I need to access page field values annotated with 
ActivationRequestParameters in order to retrieve the values. Reflection 
doesnt work, because the fields are private and a 
java.lang.IllegalAccessException is thrown. Whats the right way to 
retrieve the values / activation request parameters?

Regards
Markus

I don't know if it suits to your case, but you could use
ComponentEventLinkEncoder to decode the request path... This will return you
an object from which you can extract activation context values.

Hope that helps

Actually, not exactly, it uses an event handler to read values and add them
in the current link.

Why not just @Inject'ing the Request and using the TypeCoercer to do the  
needed conversions? I haven't read the ActivationRequestParameterWorker  
source yet, but I guess that's exactly what it does.

Re: Retrieve ActivationRequestParameters in custom PageResponseRenderer

Posted by Josh Canfield <jo...@gmail.com>.
Yes, the problem is that you are advising every advisable
page/component/service in the system. This includes base classes; when
you've already advised the base class then the interface won't be
added and therefore the method won't exist in the transformation.

Try only adding the interface to classes that have fields with the
annotation you are looking for.

Re: Retrieve ActivationRequestParameters in custom PageResponseRenderer

Posted by Josh Canfield <jo...@gmail.com>.
Right... coding in email so I missed the different type signature.

Apparently findMethods has been deprecated in favor of
List<TransformMethod> matchMethods(Predicate<TransformMethod> predicate)
Finds all methods matched by the provided predicate.

Which returns the TransformMethod which you want to add advice. Your
predicate would be by name and hopefully only find one method!

So you want something like:

List<TransformMethod> methods = transformation.matchMethods(new
Predicate<TransformMethod>()
            {
                public boolean accept(TransformMethod object)
                {
                    return method.getName().equals("extractRequestParameters");
                }
            });

if ( methods.size() != 1 ) throw new RuntimeException("Expected 1
extractRequestParameters method, found " + methods.size();

methods.get(0).addAdvice(...)

Again, I'm doing this from email with no compiler/ide so I could be
off. There might be a smarter way to do it, but it seems like if you
know the method exists you should just find it instead of
getOrCreate'ing it.

Re: Retrieve ActivationRequestParameters in custom PageResponseRenderer

Posted by Josh Canfield <jo...@gmail.com>.
Hmm... just took a look at the code again and I think I see the problem.

///// This creates the method body if your class doesn't already implement it:
transformation.addImplementedInterface(RequestParameterExtractor.class);

TransformMethodSignature extractMethod = new
TransformMethodSignature(Modifier.PUBLIC,
    "Map<String, String>", "extractRequestParameters", null, null);

/////  This is probably commented out because it always returns.
// if (transformation.isDeclaredMethod(extractMethod)) {
//    return;
// }

///// This is apparently trying to re-create the method.
transformation.getOrCreateMethod(extractMethod).addAdvice(new
ComponentMethodAdvice(){

You should call transformation.findMethods(filter); instead of
getOrCreateMethod. I'm not sure why the getOrCreate is trying to
implement the method if it's already there, but I'd guess it has
something to do with your new TransformMethodSignature.

Yes, I also removed the Generic Map from the Interface.

Just checked in debug method: the method indeed already exists 
(breakpoint: line 1443 InternalClassTransformationImpl). But how come? 
Its never added through my code.

Re: Retrieve ActivationRequestParameters in custom PageResponseRenderer

Posted by Josh Canfield <jo...@gmail.com>.
Did you take the type parameters off of the interface too (return a
raw map)? Have you looked at with a debugger? Stick a breakpoint right
before the exception and take a look at the methods in the ctclass.

I can't look at it now but I'll try to reproduce the problem tonight.

public interface RequestParameterExtractor {
     Map<String, String> extractRequestParameters();
}

is not equal to:

      TransformMethodSignature extractMethod = new 
TransformMethodSignature(Modifier.PUBLIC,
             "Map<String, String>", "extractRequestParameters", null, null);

?

Re: Retrieve ActivationRequestParameters in custom PageResponseRenderer

Posted by Christophe Cordenier <ch...@gmail.com>.
Hi !

Tapestry 5.2 has a brand new API for class manipulation in worker, you have
to provide the method signature and implement the logic in a
ComponentMethodAdvice (see PropertyWorker sources to have a simple example)

Re: Retrieve ActivationRequestParameters in custom PageResponseRenderer

Posted by Markus Feindler <Ma...@gmx.de>.
  So, I tried to follow your advice, but I don't see how to add a new 
method after calling 
"transformation.addImplementedInterface(MyInterface.class)". The 
documentation states to use transformation.getOrCreateMethod, but where 
to define the message body?

Re: Retrieve ActivationRequestParameters in custom PageResponseRenderer

Posted by Christophe Cordenier <ch...@gmail.com>.
Actually,

I would implement a ClassTransformation and add it to
contributeComponentClassTransformWorker (see Tapestry Module), This worker
should add and implement an interface that contains the method to extract
useful information from the page

Then in your PageResponseRenderer, you can use ComponentSource to get the
page instance, cast it to your interface and call the method.

Re: Retrieve ActivationRequestParameters in custom PageResponseRenderer

Posted by Markus Feindler <Ma...@gmx.de>.
  Thats the class I discovered earlier at work.

Now my question is how to get ClassTransformation and 
MutableComponentModel from the Page Object in the PageResponseRenderer?

Thanks for you help/hints.

Hi

Logic is enclosed in ActivationRequestParameterWorker, i think you can adapt
this to your needs and extract values. At the moment, I don't see any other
way to identify ActivationRequestParameters during link creation.

This only works for the current request. I need to get the parameters, 
which will be set for the next request/redirect. It would be possible to 
write get methods for the ActivationRequestParameters, but that would 
not be the right way. I need to find out how that is solved internally.

Oh sorry, i had mis-read your first message. I didn't get deep into this new
feature at the time, but at first glance, i would say you can get them from
Request directly. Maybe, you can implement a worker that will be in charge
of implementing an interface that will contain the method that return the
values.

I will go deeper to see if there is not a more simple way of doing this.

Hi

So why not passivate the page, see PageActivationContextCollector ? This is
how it works to create links.

Re: Retrieve ActivationRequestParameters in custom PageResponseRenderer

Posted by Markus Feindler <Ma...@gmx.de>.
  No, Im trying to upgrade "my" portlet implementation from 5.1 to 5.2 
and up to now the activationrequestparameters aren't put in the url, 
cause I have to adjust my former 5.1 custom response renderer. If the 
Request is an ActionRequest (see Portlet lifecycle) you can't write 
output into a stream instead a redirect is done internally in the 
portlet container. Therefore I have to add the parameters to the 
ActionReponse (_actionResponse.setRenderParameter). In order to do so I 
need to get the parameters.
