I've just noticed that in certain circumstances having a GAE/J JDO persistent detachable class like: @PersistenceCapable(identityType = IdentityType.APPLICATION, detachable="true")
may also cause: com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException: This application is out of date, please click the refresh button on your browser. at com.google.gwt.user.client.rpc.impl.RequestCallbackAdapter.onResponseReceived (RequestCallbackAdapter.java:204) at com.google.gwt.http.client.Request.fireOnResponseReceivedImpl (Request.java:264) at com.google.gwt.http.client.Request.fireOnResponseReceivedAndCatch (Request.java:236) at com.google.gwt.http.client.Request.fireOnResponseReceived (Request.java:227) 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 com.google.gwt.dev.shell.MethodAdaptor.invoke(MethodAdaptor.java: 103) at com.google.gwt.dev.shell.mac.MethodDispatch.invoke (MethodDispatch.java:71) at org.eclipse.swt.internal.carbon.OS.ReceiveNextEvent(Native Method) at org.eclipse.swt.widgets.Display.sleep(Display.java:3801) at com.google.gwt.dev.SwtHostedModeBase.sleep(SwtHostedModeBase.java: 241) at com.google.gwt.dev.SwtHostedModeBase.processEvents (SwtHostedModeBase.java:236) at com.google.gwt.dev.HostedModeBase.pumpEventLoop (HostedModeBase.java:558) at com.google.gwt.dev.HostedModeBase.run(HostedModeBase.java:405) at com.google.gwt.dev.HostedMode.main(HostedMode.java:232) Unfortunately I've spent a lot of time of useless troubleshooting to reach this conclusion, since the exception message and trace didn't indicated nothing to put me in the right direction, and the server logs didn't pointed out any problem at all.
