Hi Filip, You're right. I will not forget the advice. I was thinking of the Page object when I answer the thread, sorry. Not the "ComponentSource" service.

Adamsen [mailto:[EMAIL PROTECTED] Envoyé : mardi 11 mars 2008 13:12 À : Tapestry users Objet : Re: Page class annotations (was Re: Checking for a logged in user globally) Hi, Cordenier, that's a VERY complicated way to get the class, when, in fact, getClass() on the Component returned by ComponentSource works just fine. So that's not the problem. No, I think Andreas forgot to add @Retention(RetentionPolicy.RUNTIME) to his annotation, simple as that. Hope this helps. :) -Filip Cordenier Christophe skrev: > To resolve the class of a component, you have to use the "ComponentResources" > class. > It contains the componentModel that allows you to the class of the > "coreComponent" by using the method "getComponentClassName". > > With this method you can resolve the "Real" class of your component or page. > > There is also the ComponentClassResolver service that allows you to access > information on the component class. > > Check for example the code of "PageElementFactoryImpl" that uses this service > to instantiate components. > > -----Message d'origine----- > De : Andreas Pardeike [mailto:[EMAIL PROTECTED] > Envoyé : mardi 11 mars 2008 11:10 > À : Tapestry users > Objet : Page class annotations (was Re: Checking for a logged in user > globally) > > Great.
