Strange Null Pointer in HibernateEntityHome
pedrosena Jan 21, 2009 7:57 PMHi Guys, I'm getting the following exception:
java.lang.NullPointerException at org.jboss.seam.framework.Home.updatedMessage(Home.java:55) at org.jboss.seam.framework.HibernateEntityHome.update(HibernateEntityHome.java:41) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jboss.seam.util.Reflections.invoke(Reflections.java:22) at org.jboss.seam.intercept.RootInvocationContext.proceed(RootInvocationContext.java:31) at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:56) at org.jboss.seam.transaction.RollbackInterceptor.aroundInvoke(RollbackInterceptor.java:28) at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:68) at org.jboss.seam.core.BijectionInterceptor.aroundInvoke(BijectionInterceptor.java:77) at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:68) at org.jboss.seam.transaction.TransactionInterceptor$1.work(TransactionInterceptor.java:40) at org.jboss.seam.util.Work.workInTransaction(Work.java:47) at org.jboss.seam.transaction.TransactionInterceptor.aroundInvoke(TransactionInterceptor.java:34) at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:68) at org.jboss.seam.core.MethodContextInterceptor.aroundInvoke(MethodContextInterceptor.java:44) at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:68) at org.jboss.seam.intercept.RootInterceptor.invoke(RootInterceptor.java:107) at org.jboss.seam.intercept.JavaBeanInterceptor.interceptInvocation(JavaBeanInterceptor.java:166) at org.jboss.seam.intercept.JavaBeanInterceptor.invoke(JavaBeanInterceptor.java:102) at br.com.netsar.infra.persistence.global.NetSarCustomerHome_$$_javassist_0.update(NetSarCustomerHome_$$_javassist_0.java) at br.com.netsar.infra.persistence.TestHome$2.testComponents(TestHome.java:83) at org.jboss.seam.mock.AbstractSeamTest$ComponentTest.run(AbstractSeamTest.java:163) at br.com.netsar.infra.persistence.TestHome.testNetSarCustomerHome(TestHome.java:91)
And here is my testNetSarCustomerHome snippet:
NetSarCustomerHome customerHome = (NetSarCustomerHome) getValue("#{netSarCustomerHome}"); customerHome.setId(2); NetSarCustomer customer = customerHome.find(); assert customer.getTradingName() != null; String backup = customer.getTradingName(); String newTradingName = "NEW TRADING NAME!!"; customer.setTradingName(newTradingName); customerHome.update();
The null pointer is ocurring in the last line, when I make the update.
The most strange thing is that my update is being commited to my database, so maybe is some kind of bug?
All my Homes where conversation scoped, I changed it to Stateless Scope(what I believe that is the most appropriate) and this error started to occur.
Am I wrong to make my Homes Stateless scoped ??
Thanks,
Pedro Sena
