I am trying to implement a simple TabGroup using <a href="http://tapestry.apache.org/environmental-services.html" rel="nofollow">environmental services</a>. My code looks like this: <pre><code>public class TabPanel { ... @Inject private Environment environment; ... void beginRender() { environment.push(TabContext.class, new TabContext() { public boolean isActiveTab(String tabId) { return active != null && active.equals(tabId); } }); } } public interface TabContext { boolean isActiveTab(String tabId); } public class Tab { ... @Environmental private TabContext tabContext; @Inject private ComponentResources resources; ... private boolean isActiveAndEnabled() { return tabContext.isActiveTab(resources.getId()) && !disabled; } } </code></pre> When this code is executed, it throws following exception: <pre class="lang-none prettyprint-override"><code>java.lang.ClassFormatError: Illegal field modifiers in class TabContext </code></pre> I found part of the answer in the old thread: "... an interface like this should not be in the components package to begin with." My question is then: where should I move TabContext interface? Following the rule#1 I am posting the entire stack trace: <pre class="lang-none prettyprint-override"><code>java.lang.ClassFormatError: Illegal field modifiers in class

Guidance

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.
