[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-3211) Serialization of transient fields on converstion scoped components in clustered enviroment

Serialization of transient fields on converstion scoped components in clustered enviroment ------------------------------------------------------------------------------------------ Key: JBSEAM-3211 URL: https://jira.jboss.org/jira/browse/JBSEAM-3211 Project: Seam Issue Type: Bug Components: Core, EJB3 Affects Versions: 2.0.3.CR1 Environment: jboss 4.2.2.GA java 6 x64 windows vista 64bit Reporter: Tomaz Cerar I was debuging one of problems that has shown up on our tests when running in cluster. After adding some debuging code to jbossweb I have finally tracked it down and I am almost 100% sure it is a bug in Seam. here is scenario: I have SFSB that runs in Conversation scope and I have injected lots of various components. and some of those components aren't serializable, so I marked them transient so I wouldnt get any exceptions while serialization. But when I run this code with <distributable /> enabled I allways get exception Non Serializable attribute. But if serialization is done manualy(just to try) everything goes trough fine. I have modifed jbossweb so I got better exception reporting for this scenarios(as naming which parameter), as I found out that seam is trying to put also my transient field in session scope for needs of conversation: error message I got was: {noformat} 12:32:51,903 ERROR [SeamPhaseListener] [] uncaught exception java.lang.IllegalArgumentException: attribute: 'org.jboss.seam.CONVERSATION#12$podporaProdaji' of value: 'si.banka_koper.ws.ppbackend.PodporaProdajiCaching@5092eb76' is not serializable! at

java.lang.Thread.run(Thread.java:674) {noformat} as I understand seam trys to put everything that is in converstion scope in session event even it is not marked with @Out or marked transient. the compononent is marked only with @In and in that case I don't see why seam sould put it in session as it can be injected anytime... sample code: {code} Scope(ScopeType.CONVERSATION) @Local @Stateful public class DepozitWizardAction implements DepozitWizard, Serializable { private transient static final Logger log = Logger.getLogger(DepozitWizardAction.class); @In private transient PodporaProdaji podporaProdaji; public void someMethod(){ podporaProdaji.callSomeMethod(); } } {code}
