    <p>i used the sample mail rcp application to test out the common navigator framework. I added a view and attached it to my contentprovider. Unfortunately nothing is shown in my view, no function from my contentprovider or labelprovider even get's called.</p> <p>Here is my plugin.xml</p> <pre> &lt;extension id="application" point="org.eclipse.core.runtime.applications"&gt; &lt;application&gt; &lt;run class="rcptest.Application"&gt; &lt;/run&gt; &lt;/application&gt; &lt;/extension&gt; &lt;extension point="org.eclipse.ui.perspectives"&gt; &lt;perspective name="RCP Perspective" class="rcptest.Perspective" id="RCPTest.perspective"&gt; &lt;/perspective&gt; &lt;/extension&gt; &lt;extension point="org.eclipse.ui.views"&gt; &lt;view name="Message" allowMultiple="true" icon="icons/sample2.gif" class="rcptest.View" id="RCPTest.view"&gt; &lt;/view&gt; &lt;view name="Mailboxes" allowMultiple="true" icon="icons/sample3.gif" class="rcptest.NavigationView" id="RCPTest.navigationView"&gt; &lt;/view&gt; &lt;view class="org.eclipse.ui.navigator.CommonNavigator" icon="icons/sample.gif" id="de.meinss.test" name="My Common Navigator" restorable="true"&gt; &lt;/view&gt; &lt;/extension&gt; &lt;extension point="org.eclipse.ui.commands"&gt; &lt;category name="Mail" id="RCPTest.category"&gt; &lt;/category&gt; &lt;command name="Open Mailbox" description="Opens a mailbox" categoryId="RCPTest.category" id="RCPTest.open"&gt; &lt;/command&gt; &lt;command name="Open Message Dialog" description="Open a message dialog" categoryId="RCPTest.category" id="RCPTest.openMessage"&gt; &lt;/command&gt; &lt;/extension&gt; &lt;extension point="org.eclipse.ui.bindings"&gt; &lt;key commandId="RCPTest.open" schemeId="org.eclipse.ui.defaultAcceleratorConfiguration" sequence="CTRL+2"&gt; &lt;/key&gt; &lt;key commandId="RCPTest.openMessage" schemeId="org.eclipse.ui.defaultAcceleratorConfiguration" sequence="CTRL+3"&gt; &lt;/key&gt; &lt;key commandId="org.eclipse.ui.file.exit" schemeId="org.eclipse.ui.defaultAcceleratorConfiguration" sequence="CTRL+X"&gt; &lt;/key&gt; &lt;/extension&gt; &lt;extension id="product" point="org.eclipse.core.runtime.products"&gt; &lt;product application="RCPTest.application" name="RCP Product"&gt; &lt;property name="aboutText" value="RCP Mail template created by PDE"&gt; &lt;/property&gt; &lt;property name="windowImages" value="icons/sample2.gif"&gt; &lt;/property&gt; &lt;property name="aboutImage" value="product_lg.gif"&gt; &lt;/property&gt; &lt;/product&gt; &lt;/extension&gt; &lt;extension point="org.eclipse.ui.navigator.viewer"&gt; &lt;viewer viewerId="de.meinss.test"&gt; &lt;/viewer&gt; &lt;viewerContentBinding viewerId="de.meinss.test"&gt; &lt;includes&gt; &lt;contentExtension pattern="RCPTest.navigatorContent1"&gt; &lt;/contentExtension&gt; &lt;/includes&gt; &lt;/viewerContentBinding&gt; &lt;viewerActionBinding viewerId="de.meinss.test"&gt; &lt;includes&gt;&lt;/includes&gt; &lt;/viewerActionBinding&gt; &lt;/extension&gt; &lt;extension point="org.eclipse.ui.perspectiveExtensions"&gt; &lt;perspectiveExtension targetID="*"&gt; &lt;view id="de.meinss.test" ratio="0.5" relationship="stack" relative="org.eclipse.ui.navigator.ProjectExplorer"&gt; &lt;/view&gt; &lt;/perspectiveExtension&gt; &lt;/extension&gt; &lt;extension point="org.eclipse.ui.navigator.navigatorContent"&gt; &lt;navigatorContent activeByDefault="true" contentProvider="TreeContentProvider" icon="icons/sample.gif" id="RCPTest.navigatorContent1" labelProvider="TreeLabelProvider" name="meineigenes" priority="normal" providesSaveables="false"&gt; &lt;possibleChildren&gt; &lt;instanceof value="java.lang.String"&gt; &lt;/instanceof&gt; &lt;/possibleChildren&gt; &lt;/navigatorContent&gt; &lt;/extension&gt; </pre> <p>The classes TreeContentProvider and TreeLabelprovider exist and print out to the console if they are called, which they are not. What I'm doing wrong?</p> <p>Thanks for reading!</p> <p>Markus</p>

    1. COPersonally I wouldn't use the common navigator. I did in my application and it was a mistake. I don't know what your use cases are, but do understand that this component is really not a first-class component, it has limited features and really don't add that much value. If you need plugins to extend your tree, you can easily write your own extension point and be in control of the features.

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).
