I get an exception, that I cannot relate to where it is thrown. It happens, when I try to read a property of a stateful session bean inside a JSP using the EL. This property is a simple getter inside the component. The component has an "@In" refrence to the seam identity component, but it is not used inside the getter. The exception shows up spontaniously - the behaviour is NOT consistent and cannot reliably reproduced. The same exception happens for the '#{org.jboss.seam.core.localeSelector}' component.
My first guess is, that the components are not yet instantiated, when the getter is read. But since that happens automagically, I have no idea, what could cause this behaviour. I hope somebody can give me a hint on where to look for the cause of the exception Thanks this is the last part of the stack trace. | .... | Caused by: javax.faces.el.EvaluationException: Cannot get value for expression '#{org.jboss.seam.security.identity}' | at org.apache.myfaces.el.ValueBindingImpl.getValue(ValueBindingImpl.java:402) | at org.jboss.seam.core.Expressions$1.getValue(Expressions.java:69) | at org.jboss.seam.Component.getInstanceFromFactory(Component.java:1684) | at org.jboss.seam.Component.getInstance(Component.java:1633) | at org.jboss.seam.Component.getInstance(Component.java:1610) | at org.jboss.seam.Component.getValueToInject(Component.java:1885) | at org.jboss.seam.Component.injectAttributes(Component.java:1368) | at org.jboss.seam.Component.inject(Component.java:1195) | at org.jboss.seam.interceptors.BijectionInterceptor.aroundInvoke(BijectionInterceptor.java:46) | at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:69) | at org.jboss.seam.interceptors.MethodContextInterceptor.aroundInvoke(MethodContextInterceptor.java:27) | at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:69) | at org.jboss.seam.intercept.RootInterceptor.invoke(RootInterceptor.java:103) | at org.jboss.seam.intercept.SessionBeanInterceptor.aroundInvoke(SessionBeanInterceptor.java:53) | at sun.reflect.GeneratedMethodAccessor8647.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | at org.jboss.ejb3.interceptor.InvocationContextImpl.proceed(InvocationContextImpl.java:118) | at org.jboss.ejb3.interceptor.EJB3InterceptorsInterceptor.invoke(EJB3InterceptorsInterceptor.java:63) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) | at org.jboss.ejb3.entity.ExtendedPersistenceContextPropagationInterceptor.invoke(ExtendedPersistenceContextPropagationInterceptor.java:57) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) | at org.jboss.ejb3.entity.TransactionScopedEntityManagerInterceptor.invoke(TransactionScopedEntityManagerInterceptor.java:54) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) | at org.jboss.ejb3.AllowedOperationsInterceptor.invoke(AllowedOperationsInterceptor.java:46) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) | at org.jboss.aspects.tx.TxPolicy.invokeInCallerTx(TxPolicy.java:126) | ... 93 more | Caused by: java.lang.NullPointerException | at org.jboss.mx.loading.RepositoryClassLoader.findClass(RepositoryClassLoader.java:620) | at java.lang.ClassLoader.loadClass(ClassLoader.java:306) | at org.jboss.mx.loading.RepositoryClassLoader.loadClassImpl(RepositoryClassLoader.java:464) | at org.jboss.mx.loading.RepositoryClassLoader.loadClass(RepositoryClassLoader.java:405) | at java.lang.ClassLoader.loadClass(ClassLoader.java:251) | at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319) | at org.jboss.seam.jsf.SeamApplication11.getPropertyResolver(SeamApplication11.java:197) | at org.apache.myfaces.el.ELParserHelper$MyPropertySuffix.evaluate(ELParserHelper.java:532) | at org.apache.commons.el.ComplexValue.evaluate(ComplexValue.java:145) | at org.apache.myfaces.el.ValueBindingImpl.getValue(ValueBindingImpl.java:383) | ... 119 more | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4045263#4045263 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4045263 _______________________________________________ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
