I am working on a large application (greater than 500K lines of code) written using GWT. I am working on new screen for the application, and have come across a problem with the code splitting as follows:
- The code works successfully when run in Development Mode. - The code fails with a ClassCastException (stack trace below) when the code is compiled to javascript and run within the browser. - If I create the class directly (not using GWT.runAsync()), the problem does not occur. - I have attempted to create a simple testcase to demonstrate the problem, but when I do this the problem no longer occurs. - The ClassCastException occurs within a custom widget that was developed for this application, and is used in hundreds of other places in the application without any similar problems. - Due to the size of the application, code splitting is used extensively. A stack trace of the error is as follows (compiled with -style DETAILED) java.lang.ClassCastException: at Unknown.java_lang_ClassCastException_ClassCastException__V(Unknown Source) at Unknown.com_google_gwt_lang_Cast_dynamicCast__Ljava_lang_Object_2ILjava_lang_Object_2(Unknown Source) at Unknown.au_edu_wa_eddept_irt_client_ui_DetScrollableGrid_$calculateDimensions__Lau_edu_wa_eddept_irt_client_ui_DetScrollableGrid_2V(Unknown Source) at Unknown.au_edu_wa_eddept_irt_client_ui_DetScrollableGrid_$refreshData__Lau_edu_wa_eddept_irt_client_ui_DetScrollableGrid_2V(Unknown Source) at Unknown.au_edu_wa_eddept_irt_client_ui_SortableDetScrollableGrid_$sort__Lau_edu_wa_eddept_irt_client_ui_SortableDetScrollableGrid_2V(Unknown Source) at Unknown.au_edu_wa_eddept_irt_client_ui_SortableDetScrollableGrid_$setDisplayData__Lau_edu_wa_eddept_irt_client_ui_SortableDetScrollableGrid_2Ljava_util_List_2V(Unknown Source) at Unknown.au_edu_wa_eddept_irt_client_panel_search_StudentSearchDialog$AsyncCallbackDoStudentSearch_$onSuccess__Lau_edu_wa_eddept_irt_client_panel_search_StudentSearchDialog$AsyncCallbackDoStudentSearch_2Lau_edu_wa_eddept_irt_client_rpc_Dispatch_2V(Unknown Source) at Unknown.au_edu_wa_eddept_irt_client_panel_search_StudentSearchDialog$AsyncCallbackDoStudentSearch_onSuccess__Ljava_lang_Object_2V(Unknown Source) at Unknown.au_edu_wa_eddept_irt_client_rpc_SecuredAsyncCallback_$onSuccess__Lau_edu_wa_eddept_irt_client_rpc_SecuredAsyncCallback_2Lau_edu_wa_eddept_irt_client_rpc_Dispatch_2V(Unknown Source) at Unknown.au_edu_wa_eddept_irt_client_rpc_SecuredAsyncCallback_onSuccess__Ljava_lang_Object_2V(Unknown Source) at Unknown.com_google_gwt_user_client_rpc_impl_RequestCallbackAdapter_$onResponseReceived__Lcom_google_gwt_user_client_rpc_impl_RequestCallbackAdapter_2Lcom_google_gwt_http_client_Request_2Lcom_google_gwt_http_client_Response_2V(Unknown Source) at Unknown.com_google_gwt_http_client_Request_$fireOnResponseReceived__Lcom_google_gwt_http_client_Request_2Lcom_google_gwt_http_client_RequestCallback_2V(Unknown Source) at Unknown.com_google_gwt_http_client_RequestBuilder$1_onReadyStateChange__Lcom_google_gwt_xhr_client_XMLHttpRequest_2V(Unknown Source) at Unknown.this$static.onreadystatechange<(Unknown Source) at Unknown.com_google_gwt_core_client_impl_Impl_apply__Ljava_lang_Object_2Ljava_lang_Object_2Ljava_lang_Object_2Ljava_lang_Object_2(Unknown Source) at Unknown.com_google_gwt_core_client_impl_Impl_entry0__Ljava_lang_Object_2Ljava_lang_Object_2Ljava_lang_Object_2Ljava_lang_Object_2(Unknown Source) at Unknown.anonymous(Unknown Source) at Unknown.anonymous(Unknown Source) Any suggestions on how I should proceed to find a resolution for this problem? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
