My application works fine in DevMode but after deployment on appengine, I get JavascriptException
. I have a CellBrowser
with 3 levels. What is strange is that the exception only occurs on some element of the first and third level. The behavior is correct, meaning that when I select a first level element, the corresponding elements shows in the second level. I have a class that implements UncaughtExceptionHandler
where I log the stack trace:
@Override public void onUncaughtException(Throwable e) { StringBuffer sb = new StringBuffer(); sb.append("Exception type: " + e.getClass()).append("\n"); sb.append("Message: ").append(e.getMessage()).append("\n"); Window.alert(sb.toString()); if (e instanceof JavaScriptException) { Window.alert("JSException"); if (e.getStackTrace().length == 0) { e.fillInStackTrace(); } sb.append(e.getClass()).append(" - ").append(e.getMessage()).append( "\n"); for (StackTraceElement stackTrace : e.getStackTrace()) { sb.append(stackTrace.getClassName()).append(".").append( stackTrace.getMethodName()).append("(").append( stackTrace.getFileName()).append(":").append( stackTrace.getLineNumber()).append(")"); sb.append("\n"); } Window.alert(sb.toString()); }
When the exception occurs after selecting one element of the CellBrowser
, the log is:
Exception type: class com.google.gwt.core.client.JavaScriptException Message: (TypeError): Cannot read property 'firstChild' of undefined class com.google.gwt.core.client.JavaScriptException - (TypeError): Cannot read property 'firstChild' of undefined Unknown.com_google_gwt_dom_client_DOMImpl_$getFirstChildElement__Lcom_google_gwt_dom_client_DOMImpl_2Lcom_google_gwt_dom_client_Element_2Lcom_google_gwt_dom_client_Element_2(null:-1) Unknown.com_google_gwt_user_cellview_client_CellBrowser$BrowserCellList_getCellParent__Lcom_google_gwt_dom_client_Element_2Lcom_google_gwt_dom_client_Element_2(null:-1) Unknown.com_google_gwt_user_cellview_client_CellList_resetFocusOnCell__Z(null:-1) Unknown.com_google_gwt_user_cellview_client_AbstractHasData$View$1_execute__V(null:-1) Unknown.com_google_gwt_core_client_impl_SchedulerImpl_runScheduledTasks__Lcom_google_gwt_core_client_JsArray_2Lcom_google_gwt_core_client_JsArray_2Lcom_google_gwt_core_client_JsArray_2(null:-1) Unknown.com_google_gwt_core_client_impl_SchedulerImpl_$flushPostEventPumpCommands__Lcom_google_gwt_core_client_impl_SchedulerImpl_2V(null:-1) Unknown.com_google_gwt_core_client_impl_SchedulerImpl$Flusher_execute__Z(null:-1) Unknown.com_google_gwt_core_client_impl_SchedulerImpl_execute__Lcom_google_gwt_core_client_Scheduler$RepeatingCommand_2Z(null:-1) Unknown.com_google_gwt_core_client_impl_Impl_apply__Ljava_lang_Object_2Ljava_lang_Object_2Ljava_lang_Object_2Ljava_lang_Object_2(null:-1) Unknown.com_google_gwt_core_client_impl_Impl_entry0__Ljava_lang_Object_2Ljava_lang_Object_2Ljava_lang_Object_2Ljava_lang_Object_2(null:-1)
Do you know if it's a problem with my code, or if it's a GWT compiler bug?
I also try to run the compiled version of my app locally but I always get the message `GWT module may need to be (re)compiled). I don't understand because in Eclipse click I run the Gwt Compile Project command.
Thanks
