You should be seeing some logged console messages about private variables. Only private instance variables may have annotations on them; yours is "package private" not private.

Hi List, I'm trying to inject via @Inject annotation a service (internal service RequestPageCache) into a component: public class Menu { @Inject("RequestPageCache") RequestPageCache requestPageCache; public String getPageName() { ComponentResources pageResources= resources.getPage ().getComponentResources(); String pageClassName= pageResources.getCompleteId(); Page page= requestPageCache.getByClassName(pageClassName); return page.getName(); } } so...while rendering the page with the menu component <div id="leftside"> <div id="menu"> <ul> <li> ${pageName} </li> </ul> </div> </div> a null pointer exception occures, because "requestPageCache" is null. What is getting wrong? Is RequestPageCache not injectable? What I want: I just try to get the page of the component. Then the menu component should highlight by providing a special css-class the corresponding menu item of the <ul><li>-list for the active page. Therefore the menu component must know the current page that is rendered. In Tapestry 3 is just call the method getPage of the component. Now every component has no parent class... While we are talking about injection: the docs are a little bit confusing: @Inject @Service("xxx") (which did not work with 5.0.3, because Service annotation does not exist) or @Inject("xxx") or @Inject( "service:xxx" ) (what kind of prefixes (service:) exists and what meaning have they?) sometimes: @Inject ("alias:request" )...is there somewhere a list with all objects that are able to be injected from tapestry-core? thanks for any help cheers Michael --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
