    <p>I must be missing something simple, but I'm stuck. I created a FormPanel in gwt that, according to firebug sends the request. the link works, as I copied the requestlink from firebug and tried it natively in a browser window. Yes, client and server host are the same --> localhost. But the answer doesn't arrive at gwt. Not even the client browser - firebug shows no result eighter.</p> <p>This is my little form:</p> <pre><code> Button form = new Button ("SendForm", new ClickHandler() { @Override public void onClick(ClickEvent event) { logger.log(Level.FINER, "Creating SubmitForm..."); TextBox cmd = new TextBox(); cmd.setName("cmd"); cmd.setText("GetMenuitemList"); Button sendbutton = new Button("Senden"); logger.log(Level.FINEST, "Creating grid..."); Grid grid = new Grid(1, 2); grid.setWidget(0, 0, new Label("Command")); grid.setWidget(0, 1, cmd); VerticalPanel vPan = new VerticalPanel(); //vPan.add(grid); vPan.add(sendbutton); logger.log(Level.FINEST, "Creating FormPanel..."); final FormPanel formPan = new FormPanel(); formPan.setMethod(FormPanel.METHOD_POST); formPan.setAction(RequestHelper.getLink("Menu.php")); logger.log(Level.FINEST, "Binding Send button..."); logger.log(Level.FINEST, "Binding SubmitHandler..."); formPan.addSubmitHandler(new SubmitHandler() { @Override public void onSubmit(SubmitEvent event) { OptionPane.showMessageDialog("Form submit", event.toDebugString(), MessageType.INFO, true); } }); logger.log(Level.FINEST, "Binding SubmitCompleteHandler..."); formPan.addSubmitCompleteHandler(new SubmitCompleteHandler() { @Override public void onSubmitComplete(SubmitCompleteEvent event) { OptionPane.showMessageDialog("Form SubmitComplete", event.toDebugString(), MessageType.INFO, true); } }); logger.log(Level.FINEST, "Adding grid to formpan..."); formPan.add(grid); formPan.add(vPan); logger.log(Level.FINEST, "Creating DialogBox..."); final DialogBox box = OptionPane.createClosableBox("TestForm", true); sendbutton.addClickHandler(new ClickHandler() { @Override public void onClick(ClickEvent event) { formPan.submit(); box.hide(); } }); box.add(formPan); box.center(); } }); </code></pre> <p>The expected answer looks like this:</p> <pre><code>{"sessionid":"6dbqibo25e0bn46fldqh37psj5","data":[{"title":"Start","Controller":"Start","Action":"Index","tooltip":"Startseite, Begr\u00fc\u00dfung","prefetch":"1"},{"title":"Register","Controller":"Person","Action":"Index","tooltip":"Neue Benutzer registrieren","prefetch":"0"},{"title":"Daten","Controller":"Contact","Action":"Index","tooltip":"Die eigenen Daten bearbeiten","prefetch":"1"},{"title":"Teilnehmerlisten","Controller":"Lists","Action":"Index","tooltip":"Listen der registrierten Benutzer","prefetch":"0"},{"title":"Suche","Controller":"Search","Action":"Index","tooltip":"Namenssuche nach Benutzer mit Kontaktm\u00f6glichkeit","prefetch":"1"},{"title":"Kalender","Controller":"Calendar","Action":"Index","tooltip":"Termine","prefetch":"1"},{"title":"Newsletter","Controller":"Newsletter","Action":"Index","tooltip":"Verschicken von Newslettern","prefetch":"1"},{"title":"Wettk\u00e4mpfer","Controller":"Competitor","Action":"Index","tooltip":"Zugriff auf Wettk\u00e4mpfer","prefetch":"1"},{"title":"Upload","Controller":"Upload","Action":"Index","tooltip":"Bilder, Videos o.\u00e4. hochladen","prefetch":"0"},{"title":"Administration","Controller":"Admin","Action":"Index","tooltip":"Datenbankfunktionen und Benutzerrechte","prefetch":"1"}]} </code></pre> <p>So, what is going wrong here?</p> <p>BTW, I'll use this technique for a login form. I read, its better to do this in a form than via RequestBuilder (that worked already). File upload will come later, so the form question needs an answer in any case...</p> <p>Thank you in advance. Markus</p> <p>Edit: ok, I tested on Chromium, Konqueror and Opera also - the code works. It's just firefox. Ideas to get it going with firefox? I'm a total newby in eclipse and gwt... maybe some compiler option?</p>

    1. COIf Firebug doesn't show a response, then check your server. If it does, check its console for possible errors; also check the origin: same server is not enough, you also need same scheme (http vs. https) and port! Finally, the server **must** answer with a `text/html` response for the submit-complete event to fire.

    3. CODo you reply with `Content-Type: text/html`? Firebug really tells you it didn't see a response?

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).
