[errai-dev] Good question from IRC yesterday evening

[Jonathan Fuerth]

I missed this question on IRC before leaving the office yesterday. But it's a good one, and something I think we should fix in 2.2: 



	



	

	w0mbat 	
	

hey, I am again playing with errai, errai ui and errai navigation. what i did was, I defined an @EntryPoint annotated class in my application which only adds the Navigation Panel to the RootPanel as specified here: https://docs.jboss.org/author/display/ERRAI/Errai+UI+Navigation 	
6:11 
	

	

	
w0mbat 	
	
The I have an IndexPage annotated @Templated("index.html") @Page(startingPage = true) 	

	

	
6:12 
	

	

	
w0mbat 	

	
and a LoginPage annotated @Templated("index.html") @Page(path="login") 	

	

	
6:13 
	

	

	
w0mbat 	

	
compiling works fine so war. as soon as I start "mvn gwt:run" i get: [ERROR] org.jboss.errai.ioc.client.container.IOCResolutionException: no matching bean instances for: at.w0mb.Sample.client.local.IndexPage 	

	

	
6:14 
	

	

	
w0mbat 	

	
[ERROR] at org.jboss.errai.ioc.client.container.IOCBeanManager.lookupBean(IOCBeanManager.java:475) 	

	

	
6:14 
	

	

	
w0mbat 	

	
[ERROR] at org.jboss.errai.ui.nav.client.local.spi.GeneratedNavigationGraph$2.content(GeneratedNavigationGraph.java:32) 	

	

	
6:14 
	

	

	
w0mbat 	

	
[ERROR] at org.jboss.errai.ui.nav.client.local.Navigation.makePageVisible(Navigation.java:80) 	

	

	
6:14 
	

	

	
w0mbat 	

	
[ERROR] at org.jboss.errai.ui.nav.client.local.Navigation.goTo(Navigation.java:67) 


The problem is likely that w0mbat's @Page bean isn't explicitly marked with a CDI scope, so it's not available in IOCBeanManager.lookupBean(). Is there anything I can do at Errai Navigation rebind time to ensure implicitly scoped @Page beans are treated is if they were explicitly scoped @Dependent?
