Hi, We have tried to rewrite the built-in UserManager of appfuse, and came up with our own UserManager. For the test case of our UserManager, given a code which accesses a collection field, it returns LazyInitializationException, i.e. user.getAccounts().get(0). The collection field is configured as FetchType.LAZY. Did I miss something here?? At the DAO test case, it works fine, (got some readings on AbstractTransactionalDataSourceSpringContext, and it seems like, this one solves the Lazy loading problem on the DAO test case), but when it comes to the Service test case, it fails, found out that BaseManagerTestCase extends the AbstractDependencyInjectionSpringContext and not the class DAO base test case uses. Does it matter? How come?
If I said the reason BaseManagerTestCase extends AbstractDependencyInjectionSpringContextTests instead of AbstractTransactionalDataSourceSpringContextTests was to show possible lazy-loading issues, would you believe me? ;-) If you're going to expose any of your service-layer objects through web services, you should probably initialize all the lazy collections in your DAO or Service layer. In the most recent version of AppFuse, we've removed the OpenSessionInViewFilter from web.xml. We did it to make it easier to use the same web.xml for any type of persistence framework. With that being said, I don't see a problem with using lazy-loading, so if you'd like us to change BaseManagerTestCase, please enter an issue in JIRA. We could also change it to extend AbstractAnnotationAwareTransactionalTests, which allows you to use annotations to indicate transactional methods. http://tinyurl.com/298vaw Matt
