Re: Retrieve ActivationRequestParameters in custom PageResponseRenderer
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.

Right... coding in email so I missed the different type signature.
Apparently findMethods has been deprecated in favor of
ListTransformMethod matchMethods(PredicateTransformMethod 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:
ListTransformMethod methods = transformation.matchMethods(new
PredicateTransformMethod()
{
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.

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,
MapString, String, extractRequestParameters, null, null);
/ This is probably commented out because it always returns.
// if (transformation.isDeclaredMethod(extractMethod)) {

/ 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.
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.

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.

@Christoph:
Same Error
@Josh
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.
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.

Everything looks good ... The only thing i see is that the method
signature
is not exactly the same as the one declared in the interface.

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

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) HTH 2010/9/7 Markus Feindler markus.feind...@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? 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. 2010/9/6 Markus Feindlermarkus.feind...@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. Regards markus 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. 2010/9/6 Markus Feindlermarkus.feind...@gmx.de i would say you can get them from Request directly 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. 2010/9/6 Markus Feindlermarkus.feind...@gmx.de Thats what Im doing right now for the PageActivationContext, but I also need the values for the ActivationRequestParameters (introduced in 5.2: http://tapestry.apache.org/tapestry5.2-dev/apidocs/org/apache/tapestry5/annotations/ActivationRequestParameter.html ).

Re: Retrieve ActivationRequestParameters in custom PageResponseRenderer
Actually, not exactly, it uses an event handler to read values and add them in the current link. 2010/9/6 Thiago H. de Paula Figueiredo thiag...@gmail.com On Mon, 06 Sep 2010 15:01:09 -0300, Christophe Cordenier christophe.corden...@gmail.com wrote: Hi Hi!

Re: Retrieve ActivationRequestParameters in custom PageResponseRenderer
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. Regards markus 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. 2010/9/6 Markus Feindlermarkus.feind...@gmx.de i would say you can get them from Request directly 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. 2010/9/6 Markus Feindlermarkus.feind...@gmx.de Thats what Im doing right now for the PageActivationContext, but I also need the values for the ActivationRequestParameters (introduced in 5.2: http://tapestry.apache.org/tapestry5.2-dev/apidocs/org/apache/tapestry5/annotations/ActivationRequestParameter.html ). Hi So why not passivate the page, see PageActivationContextCollector ? This is how it works to create links. 2010/9/5 Markus Feindlermarkus.feind...@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. That's not enough details. -- Josh On Sep 5, 2010, at 9:51 AM, Markus Feindlermarkus.feind...@gmx.de wrote: Need it for portlet implementation. Hi What is the purpose ?

Re: Retrieve ActivationRequestParameters in custom PageResponseRenderer
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.
