    <p>In Spring MVC I can access my beans in JSP using JstlView's exposedContextBeanNames (or exposeContextBeansAsAttributes). For example, then, in my JSP I can write (${properties.myProperty). But when the same JSP is a part of a tiles view, these properties aren't accessible. Is possible to configure Tiles properly or access these properties in another way?</p> <p>I'm using Spring MVC 3.0.2 and Tiles 2.2.1. Here's a bit of my configuration:</p> <pre><code>&lt;bean id="tilesViewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver"&gt; &lt;property name="order" value="1"/&gt; &lt;property name="viewClass" value="org.springframework.web.servlet.view.tiles2.TilesView" /&gt; &lt;/bean&gt; &lt;bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"&gt; &lt;property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/&gt; &lt;property name="order" value="2"/&gt; &lt;property name="prefix" value="/WEB-INF/views/"/&gt; &lt;property name="suffix" value=".jsp"/&gt; &lt;property name="exposedContextBeanNames"&gt; &lt;list&gt;&lt;value&gt;properties&lt;/value&gt;&lt;/list&gt; &lt;/property&gt; &lt;/bean&gt; </code></pre> <p><strong>EDIT:</strong> I've implemented Skaffman's solution.</p> <p>TilesExposingBeansViewResolver.java:</p> <pre><code>package es.kcsolutions.util.spring.servlet.view; import org.springframework.web.servlet.view.*; public class TilesExposingBeansViewResolver extends UrlBasedViewResolver { private Boolean exposeContextBeansAsAttributes; private String[] exposedContextBeanNames; public void setExposeContextBeansAsAttributes(boolean exposeContextBeansAsAttributes) { this.exposeContextBeansAsAttributes = exposeContextBeansAsAttributes; } public void setExposedContextBeanNames(String[] exposedContextBeanNames) { this.exposedContextBeanNames = exposedContextBeanNames; } @Override protected AbstractUrlBasedView buildView(String viewName) throws Exception { AbstractUrlBasedView superView = super.buildView(viewName); if (superView instanceof TilesExposingBeansView) { TilesExposingBeansView view = (TilesExposingBeansView) superView; if (this.exposeContextBeansAsAttributes != null) view.setExposeContextBeansAsAttributes(this.exposeContextBeansAsAttributes); if (this.exposedContextBeanNames != null) view.setExposedContextBeanNames(this.exposedContextBeanNames); } return superView; } } </code></pre> <p>TilesExposingBeansView.java:</p> <pre><code>package es.kcsolutions.util.spring.servlet.view; import java.util.*; import javax.servlet.http.*; import org.springframework.web.context.support.ContextExposingHttpServletRequest; import org.springframework.web.servlet.view.tiles2.TilesView; public class TilesExposingBeansView extends TilesView { private boolean exposeContextBeansAsAttributes = false; private Set&lt;String&gt; exposedContextBeanNames; public void setExposeContextBeansAsAttributes(boolean exposeContextBeansAsAttributes) { this.exposeContextBeansAsAttributes = exposeContextBeansAsAttributes; } public void setExposedContextBeanNames(String[] exposedContextBeanNames) { this.exposedContextBeanNames = new HashSet&lt;String&gt;(Arrays.asList(exposedContextBeanNames)); } protected HttpServletRequest getRequestToExpose(HttpServletRequest originalRequest) { if (this.exposeContextBeansAsAttributes || this.exposedContextBeanNames != null) return new ContextExposingHttpServletRequest(originalRequest, getWebApplicationContext(), this.exposedContextBeanNames); return originalRequest; } @Override protected void renderMergedOutputModel(Map&lt;String, Object&gt; model, HttpServletRequest request, HttpServletResponse response) throws Exception { HttpServletRequest requestToExpose = getRequestToExpose(request); exposeModelAsRequestAttributes(model, requestToExpose); super.renderMergedOutputModel(model, requestToExpose, response); } } </code></pre> <p>Spring configuration:</p> <pre><code> &lt;bean id="tilesViewResolver" class="es.kcsolutions.util.spring.servlet.view.TilesExposingBeansViewResolver"&gt; &lt;property name="order" value="1"/&gt; &lt;property name="viewClass" value="es.kcsolutions.util.spring.servlet.view.TilesExposingBeansView"/&gt; &lt;property name="exposedContextBeanNames"&gt; &lt;list&gt;&lt;value&gt;properties&lt;/value&gt;&lt;/list&gt; &lt;/property&gt; &lt;/bean&gt; </code></pre> <p>If you have some problem, take a look at TilesExposingBeansView.renderMergedOutputModel. I've made some tests, but maybe it's necessary to make a lot more.</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
