    <p>I am wondering what is the best way to add context information (like the current menu or the title of the page) to spring 3 + tiles 2 app.</p> <p>I want the system to be as easily extenable as possible, so for example my tiles config uses a wildcards, because I do not want to write a new entry for every new request handler:</p> <pre><code>&lt;tiles-definitions&gt; &lt;definition name="baseLayout" template="/WEB-INF/jsp/layout.jsp"&gt; &lt;put-attribute name="title" value="Template" /&gt; &lt;put-attribute name="header" value="/WEB-INF/jsp/header.jsp" /&gt; &lt;put-attribute name="menu" value="/WEB-INF/jsp/menu.jsp" /&gt; &lt;put-attribute name="body" value="/WEB-INF/jsp/content.jsp" /&gt; &lt;put-attribute name="footer" value="/WEB-INF/jsp/footer.jsp" /&gt; &lt;/definition&gt; &lt;definition name="**-tile" extends="baseLayout"&gt; &lt;put-attribute name="title" value="{1}" /&gt; &lt;put-attribute name="body" value="/WEB-INF/jsp/{1}.jsp" /&gt; &lt;/definition&gt; &lt;/tiles-definitions&gt; </code></pre> <p>So I guess the only choice left is to add stuff to the model. I could of course add a new model entry (e.g. MODEL_ID) for every requesthandler, like this:</p> <pre><code>@RequestMapping(value="/order/{orderId}.x") public String showOrder(ModelMap model, @PathVariable long orderId) { // do stuff model.addAttribute(Context.MODEL_ID, Context.getOrderContext()); } </code></pre> <p>and then this particular MODEL_ID is interpreted in title.jsp to show a title and in menu.jsp to highlight the current menu item.</p> <p>However, I do not like the idea of adding those lines to all request methods of all my controllers. </p> <p>I was thinking about writing an Interceptor which tries to determine the "context" based on the name of the view or requestpath, but then I have to rewrite all URLs in the interceptor and also keep them in sync with the Controllers.</p> <p>What is the correct or simpliest way to add context info to every controller to use in common tiles?</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.
