    <p>Maybe I'm missing something simple here but how do I get a method whose parameter is an interface using reflection.</p> <p>In the following case <code>newValue</code> would be a <code>List&lt;String&gt;</code> called <code>foo</code>. So I would call <code>addModelProperty("Bar", foo);</code> But this only works for me if I don't use the interface and only use <code>LinkedList&lt;String&gt; foo</code>. How do I use an interface for <code>newValue</code> and get the method from <code>model</code> that has an interface as the parameter <code>addBar(List&lt;String&gt; a0)</code>?</p> <p>Here is a more detailed example. (based on: <a href="http://www.oracle.com/technetwork/articles/javase/index-142890.html" rel="nofollow noreferrer">This example</a>)</p> <pre><code>public class AbstractController { public setModel(AbstractModel model) { this.model = model; } protected void addModelProperty(String propertyName, Object newValue) { try { Method method = getMethod(model.getClass(), "add" + propertyName, newValue); method.invoke(model, newValue); } catch (NoSuchMethodException e) { } catch (InvocationTargetException e) { } catch (Exception e) {} } } public class AbstractModel { protected PropertyChangeSupport propertyChangeSupport; protected void firePropertyChange(String propertyName, Object oldValue, Object newValue) { propertyChangeSupport.firePropertyChange(propertyName, oldValue, newValue); } } public class Model extends AbstractModel { public void addList(List&lt;String&gt; list) { this.list.addAll(list); } } public class Controller extends AbstractController { public void addList(List&lt;String&gt; list) { addModelProperty(list); } } public void example() { Model model = new Model(); Controller controller = new Controller(); List&lt;String&gt; list = new LinkedList&lt;String&gt;(); list.add("example"); // addList in the model is only found if LinkedList is used everywhere instead of List controller.addList(list); } </code></pre>

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.
