Re: [seam-dev] is there an equivalent of Seam 2 @out in CDI / Seam 3

Hi Dan and Team, Sorry to go back to this subject but I don't get the expected result from @produces. In Seam social Web client example, I tried to outject currentServiceHdl in SocialClient bean like this : @Produces @Named public OAuthServiceHandler getCurrentServiceHdl() { return currentServiceHdl; } and I get the following exception when Social client is initialized (apparently in the @Postconstruct callback) from JSF call (notice that currentServiceHdl is not in the JSF view that triggers the exception only socilaClient) : java.lang.NoClassDefFoundError: org/jboss/weld/exceptions/WeldException at org.jboss.weld.bean.AbstractClassBean.defaultPostConstruct(AbstractClassBean.java:595) at org.jboss.weld.bean.ManagedBean$ManagedBeanInjectionTarget.postConstruct(ManagedBean.java:200) at org.jboss.weld.bean.ManagedBean.create(ManagedBean.java:340) at org.jboss.weld.context.AbstractContext.get(AbstractContext.java:121) at org.jboss.weld.bean.proxy.ContextBeanInstance.getInstance(ContextBeanInstance.java:99) at org.jboss.weld.bean.proxy.ProxyMethodHandler.invoke(ProxyMethodHandler.java:87) at org.jboss.seam.social.example.webclient.org$jboss$weld$bean-jboss$classloader:id="vfs:$$$Users$antoine$Documents$Eclipse_workspaces$seam-social$$metadata$$plugins$org$jboss$ide$eclipse$as$core$JBoss_6$0_Runtime_Server1295753022377$deploy$seam-social-web-client$war"-ManagedBean-class_org$jboss$seam$social$example$webclient$SocialClient_$$_WeldClientProxy.getServiceHandlers(org$jboss$weld$bean-jboss$classloader:id="vfs:$$$Users$antoine$Documents$Eclipse_workspaces$seam-social$$metadata$$plugins$org$jboss$ide$eclipse$as$core$JBoss_6$0_Runtime_Server1295753022377$deploy$seam-social-web-client$war"-ManagedBean-class_org$jboss$seam$social$example$webclient$SocialClient_$$_WeldClientProxy.java) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) removing @Produces @Named make the exception disappears. Any clue ?
