    <p>I am using nested Asynchronous callbacks to save my front-end data to the back-end database. The data is being save into the tables the way i want them to, but it is printing that it failed. Here is the code:</p> <pre><code> if(erasync == null) erasync = GWT.create(EntityRelationService.class); AsyncCallback&lt;Void&gt; callback = new AsyncCallback&lt;Void&gt;(){ public void onFailure(Throwable caught) { String msg = caught.getLocalizedMessage(); if (caught instanceof NotFoundException) { msg = ((NotFoundException) caught).getType() + ((NotFoundException) caught).getMessage(); } System.out.println("Failed" + msg); } public void onSuccess(Void result) { if(erasync == null) erasync = GWT.create(EntityRelationService.class); AsyncCallback&lt;Void&gt; callbackOthers = new AsyncCallback&lt;Void&gt;(){ @Override public void onFailure(Throwable caught) { String msg = caught.getLocalizedMessage(); if (caught instanceof NotFoundException) { msg = ((NotFoundException) caught).getType() + ((NotFoundException) caught).getMessage(); } System.out.println("Failed" + msg); caught.printStackTrace(); } public void onSuccess(Void result) { System.out.println("Success"); } }; erasync.setEntityType(name, top, left, pname, callbackOthers); }; erasync.setProject(name, callback); </code></pre> <p>Here it prints successful for the first callback, but for the nested one it says failed though it saves the value. Here is the stack that it prints for failure:</p> <pre><code>com.google.gwt.user.client.rpc.StatusCodeException: at com.google.gwt.user.client.rpc.impl.RequestCallbackAdapter.onResponseReceived(RequestCallbackAdapter.java:192) at com.google.gwt.http.client.Request.fireOnResponseReceived(Request.java:287) at com.google.gwt.http.client.RequestBuilder$1.onReadyStateChange(RequestBuilder.java:393) at sun.reflect.GeneratedMethodAccessor21.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.google.gwt.dev.shell.MethodAdaptor.invoke(MethodAdaptor.java:103) at com.google.gwt.dev.shell.MethodDispatch.invoke(MethodDispatch.java:71) at com.google.gwt.dev.shell.OophmSessionHandler.invoke(OophmSessionHandler.java:157) at com.google.gwt.dev.shell.BrowserChannel.reactToMessagesWhileWaitingForReturn(BrowserChannel.java:1713) at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript(BrowserChannelServer.java:165) at com.google.gwt.dev.shell.ModuleSpaceOOPHM.doInvoke(ModuleSpaceOOPHM.java:120) at com.google.gwt.dev.shell.ModuleSpace.invokeNative(ModuleSpace.java:507) at com.google.gwt.dev.shell.ModuleSpace.invokeNativeObject(ModuleSpace.java:264) at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeObject(JavaScriptHost.java:91) at com.google.gwt.core.client.impl.Impl.apply(Impl.java) at com.google.gwt.core.client.impl.Impl.entry0(Impl.java:188) at sun.reflect.GeneratedMethodAccessor15.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.google.gwt.dev.shell.MethodAdaptor.invoke(MethodAdaptor.java:103) at com.google.gwt.dev.shell.MethodDispatch.invoke(MethodDispatch.java:71) at com.google.gwt.dev.shell.OophmSessionHandler.invoke(OophmSessionHandler.java:157) at com.google.gwt.dev.shell.BrowserChannel.reactToMessages(BrowserChannel.java:1668) at com.google.gwt.dev.shell.BrowserChannelServer.processConnection(BrowserChannelServer.java:401) at com.google.gwt.dev.shell.BrowserChannelServer.run(BrowserChannelServer.java:222) at java.lang.Thread.run(Thread.java:619) </code></pre> <p>Am i missing something?</p> <p>Any input will be of great help.

    2. COIt might be helpful to restructure your code to include fewer inline anonymous classes (callbacks, clickhandlers). Making your code more readable means more people will be able to answer your question, and you may even discover a bug while refactoring.

    3. COI tried to print the error stack but it is just printing failed(this is the println statement in failure method of asynchronous method). I am not sure why it is entering the Failure method.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
