    <p>I need to insert a [number of] uiBinder-based widgets into another one, at a particular spot. The inserted widget has a somewhat complicated layout, so I am trying to define it in HTML. </p> <p>referencePanel.add(...) fails with java.lang.IllegalStateException: This widget's parent does not implement HasWidgets. Don't know which widget's parent it's unhappy about - innerPanel or referencePanel. </p> <p>If the ReferenceUI object is added to RootPanel, and then it's added to the bottom of the page. But if it's added to RootPanel first, then there is a JavaScriptException Code 3 (HIERARCHY_REQUEST_ERR) when added to referencePanel. </p> <p>Any suggestions? </p> <pre><code>public class AppUIDemo extends Composite { @UiTemplate("AppUIDemo.ui.xml") interface AppUIDemoUiBinder extends UiBinder&lt;Widget, AppUIDemo&gt; { } @UiTemplate("ReferenceUI.ui.xml") interface ReferenceUIUiBinder extends UiBinder&lt;Widget, ReferenceUI&gt; { } private static AppUIDemoUiBinder uiBinder = GWT .create(AppUIDemoUiBinder.class); private static ReferenceUIUiBinder refUIBinder = GWT .create(ReferenceUIUiBinder.class); @UiField FlowPanel referencePanel; public AppUIDemo() { initWidget(uiBinder.createAndBindUi(this)); ReferenceUI reference = new ReferenceUI(refUIBinder); HTMLPanel innerPanel = reference.getRefPanel(); innerPanel.getElement().setId(HTMLPanel.createUniqueId()); referencePanel.add(innerPanel); } } </code></pre> <p>&nbsp;</p> <pre><code>public class ReferenceUI extends Composite { interface ReferenceUIUiBinder extends UiBinder&lt;Widget,ReferenceUI&gt; { } private static ReferenceUIUiBinder uiBinder = GWT .create(ReferenceUIUiBinder.class); @UiField HTMLPanel refPanel; public ReferenceUI() { initWidget(uiBinder.createAndBindUi(this)); } public CreditReferenceUI(final UiBinder&lt;Widget, CreditReferenceUI&gt; binder) { initWidget(binder.createAndBindUi(this)); } public HTMLPanel getRefPanel() { return refPanel; } } </code></pre> <p>ReferenceUI.ui.xml </p> <pre><code>&lt;!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent"&gt; &lt;ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder" xmlns:g="urn:import:com.google.gwt.user.client.ui" xmlns:gwittir="urn:import:com.totsp.gwittir.client.ui"&gt; &lt;g:HTMLPanel ui:field="referencePanel"&gt; &lt;table&gt; &lt;tr&gt; &lt;td&gt; &lt;b&gt;First Name&lt;/b&gt;&lt;/td&gt; &lt;td&gt; &lt;b&gt;Last Name&lt;/b&gt;&lt;/td&gt; &lt;td&gt; &lt;b&gt;Phone&lt;/b&gt;&lt;/td&gt; &lt;td&gt; &lt;b&gt;Fax&lt;/b&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt; &lt;gwittir:TextBox ui:field="referenceFirstName" styleName="input"/&gt;&lt;/td&gt; &lt;td&gt; &lt;gwittir:TextBox ui:field="referenceLastName" styleName="input"/&gt;&lt;/td&gt; &lt;td&gt; &lt;table&gt;&lt;tr&gt; &lt;td&gt; ( &lt;/td&gt; &lt;td&gt; &lt;gwittir:TextBox ui:field="referencePhoneAreaCode" styleName="input" maxLength="3"/&gt;&lt;/td&gt; &lt;td&gt; ) &lt;/td&gt; &lt;td&gt; &lt;gwittir:TextBox ui:field="referencePhoneNumber" styleName="input" maxLength="7"/&gt;&lt;/td&gt; &lt;td&gt; # &lt;/td&gt; &lt;td&gt; &lt;gwittir:TextBox ui:field="referencePhoneExtension" styleName="input" maxLength="25"/&gt;&lt;/td&gt; &lt;/tr&gt;&lt;/table&gt;&lt;/td&gt; &lt;td&gt; &lt;table&gt;&lt;tr&gt; &lt;td&gt; ( &lt;/td&gt; &lt;td&gt; &lt;gwittir:TextBox ui:field="referenceFaxAreaCode" styleName="input" maxLength="3"/&gt;&lt;/td&gt; &lt;td&gt; ) &lt;/td&gt; &lt;td&gt; &lt;gwittir:TextBox ui:field="referenceFaxNumber" styleName="input" maxLength="7"/&gt;&lt;/td&gt; &lt;/tr&gt;&lt;/table&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td style="text-align:right"&gt; &lt;b&gt;Address: &lt;/b&gt; Street&lt;/td&gt; &lt;td&gt; &lt;gwittir:TextBox ui:field="referenceStreet" styleName="input"/&gt;&lt;/td&gt; &lt;td colspan="2" style="width:50%"&gt; &lt;table&gt;&lt;tr&gt;&lt;td&gt; City&lt;/td&gt; &lt;td&gt;&lt;gwittir:TextBox ui:field="referenceCity" styleName="input" maxLength="25"/&gt;&lt;/td&gt; &lt;td&gt; State &lt;/td&gt; &lt;td class="state"&gt;&lt;gwittir:TextBox ui:field="referenceState" styleName="input" maxLength="2"/&gt;&lt;/td&gt; &lt;td&gt; ZIP&lt;/td&gt; &lt;td&gt;&lt;gwittir:TextBox ui:field="referenceZIP" styleName="input" maxLength="9"/&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/g:HTMLPanel&gt; &lt;/ui:UiBinder&gt; </code></pre> <p>AppUIDemo.ui.xml</p> <pre><code>&lt;!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent"&gt; &lt;ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder" xmlns:g="urn:import:com.google.gwt.user.client.ui" xmlns:gwittir="urn:import:com.totsp.gwittir.client.ui"&gt; &lt;g:HTMLPanel ui:field="basePanel"&gt; &lt;!-- &lt;div id="MainContent"&gt; --&gt; &lt;p&gt;&lt;h2&gt;&lt;b&gt;Application Demo&lt;/b&gt;&lt;/h2&gt;&lt;/p&gt; &lt;g:FlowPanel ui:field="referencePanel"&gt; &lt;/g:FlowPanel&gt; &lt;/g:HTMLPanel&gt; &lt;/ui:UiBinder&gt; </code></pre>

    1. COAre you sure you define the id for the ReferenceUI composite? (or are you sure you have a holder with the the appropriate id in you ReferencePanel?) I don't see any in the code. BTW, could you provide the UiBinder code too?

    2. COReference panel in *.ui.xml is defined as <g:HTMLPanel ui:field="referencePanel">. How would I define the id for the composite - can you point to an example? There is no local UiBinder code, UiBinder is imported from com.google.gwt.uibinder.client.UiBinder.

    3. COCan you post the UiBinder template for AppUIDemo as well as ReferenceUI? It would be nice to see exactly what the hierarchy of widgets looks like.

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).
