Hi, I posted this already at the AppEngine forum but I think this is an interface problem so I post here as well.
I’m building an application with GWT and GAE and have a problem saving data in the datastore. In my application I generate a list which consists of lists of strings, looks this way: List<List<String>> trackList; It compiles but gives me a warning: [WARN] Warnings in generated://D271BF8A9063BFFBB6E2618C9E23EF15/eventManagement/shared/HandleEventService_TypeSerializer.java' [WARN] Line 31: Referencing deprecated class 'com.google.gwt.user.client.ui.ChangeListenerCollection' And 3 other deprecated classes When I run the application and call the method for saving data I get the following error: javax.jdo.JDOException: Error creating the MetaDataManager for API "JDO" : NestedThrowables: java.lang.reflect.InvocationTargetException I think the problem is that the compiler uses old GWT classes for serialization and not the classes of the GAE. Right? Any idea how I could fix this problem? Thanks a lot. Greetings -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
