    <p>I had a project that was working ok with Spring 3.0. I've now moved to Maven to control dependencies and moved to Spring 3.1.2 jars and Spring security 3.1.1 jars.</p> <p>When I attempt to access a JSP that includes use of the security taglib (eg ) I get the error below:</p> <pre><code>javax.servlet.ServletException: javax.servlet.jsp.JspException: java.io.IOException: No visible WebSecurityExpressionHandler instance could be found in the application context. There must be at least one in order to support expressions in JSP 'authorize' tags. </code></pre> <p>In my security-context I have:</p> <pre><code>&lt;http auto-config="true" use-expressions="true" create-session="ifRequired" </code></pre> <p>From my old project:</p> <pre><code>&lt;beans:bean id="expressionHandler" class="org.springframework.security.access.expression.method.DefaultMethodSecurityExpressionHandler" /&gt; </code></pre> <p>I couldn't find that class in the packages I have for my project, so thinking it may just be a move of classes I tried:</p> <pre><code>&lt;beans:bean id="expressionHandler" class="org.springframework.security.web.access.expression.WebSecurityExpressionHandler" /&gt; </code></pre> <p>This gives me the same error.</p> <p>Spring-security dependencies I have configured at the moment: spring-security-core-3.1.1 spring-security-taglibs-3.1.1 spring-security-acl-3.1.1 spring-security-config-3.1.1 spring-security-web-3.1.1</p> <p>Am I missing a jar that would contain whatever 'use-expressions=true' needs?</p>

    1. COSo it seems WebSecurityExpressionHandler ahas been removed in Spring 3.1.1, which would explain why my application can't find an instance. https://jira.springsource.org/browse/SEC-1985 Though now I'm even more lost as presumably there is something I need to replace that functionality but I don't know what.

    3. COIt has been fixed, but I couldn't tell you how/why. It stopped complaining after a bunch of changes. I'll add an answer in a minute....

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).
