    <p>I've been working for a year now on a GWT application, and we never felt the need to use any of these frameworks or tools.</p> <p>So i feel like we're probably missing out.</p> <p>We do it "code behind" style.</p> <p>Here's a simple example on how we build our code :</p> <p>MyPanel.ui.xml :</p> <pre><code>&lt;label ui:field="label"/&gt; &lt;g:TextBox ui:field="box"/&gt; &lt;g:Button ui:field="button"/&gt; </code></pre> <p>MyPanel.java :</p> <pre><code>@UiField LabelElement label; @UiField TextBox box; @UiField Button button; MyBean myBean; Messages messages = GWT.create(Messages.class); MyServiceAsync myServiceAsync = GWT.create(MyService.class); ... protected void i18n() { label.setInnerText(messages.label()); button.setText(messages.button()); } ... @UiHandler("box") void box_onValueChange(ValueChangeEvent&lt;String&gt; event) { myBean.setText(event.getValue()); } @UiHandler("button") void button_onClick(ClickEvent event) { myServiceAsync.sendData(myBean, new AsyncCallback&lt;MyResponse&gt;() { @Override public void onSuccess(ReponseDispoBean result) { Window.alert(result.message()); } @Override public void onFailure(Throwable caught) { Window.alert(caught.getMessage()); } }); } </code></pre> <p>To communicate between panels (portions of pages, each in its own class), we use the widget's or the application's eventbus to send custom events.</p> <p>To navigate we use the places/tokenizers/activities and the historymapper</p> <p>And for unit and functionnal tests, we use <a href="https://github.com/gwt-test-utils/gwt-test-utils">gwt-test-utils</a></p> <p>And that's it. So i'm wondering : what pain those tools help with ? What compelling reason is there to use them ?</p> <p>Thanks</p>

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.
