    <p>I'm using Spring Web Flow (v. 1.0.5) and I have a JSP page that makes an AJAX call to a flow and needs to read in the XML results. That flow successfully sets an object into the FlowScope, then calls a JSP page to render the results. In the JSP page, I'd like to test whether the object has a property (say, .firstName) and if so, do something. I can access the variable in the FlowScope using JSTL expression language (by saying ${userObj}), but that just lets me spit it out. I've tried the methods below to get at it and put logic around it, with varying success.</p> <p><strong>Update: The remaining question is: How do I get the context and flow scope in the scriptlet (&lt;% %>) section?</strong></p> <pre><code>&lt;rootnode&gt; &lt;!-- Attempt 1: c:if isn't being interpreted (though ${userObj.firstName} is), it's just displaying the tags on the page. --&gt; &lt;!-- Update, I didn't have the &lt;%@ taglib directive for jstl/core. Now I do, and they're being interpreted, but it says "According to TLD or attribute directive in tag file, attribute test does not accept any expressions" How can the if/@test not accept expressions? Isn't that its whole purpose in life? --&gt; &lt;!-- Update 2, I also forgot the taglib for the rt language, which is separate, I guess (jstl/core_rt). &lt;c:if test now works properly. --&gt; &lt;c:if test="${!empty(userObj.firstName)}"&gt; &lt;test&gt;not empty&lt;/test&gt; &lt;/c:if&gt; &lt;% /* Attempt 2: This throws an error, can't resolve "context". How do I get the context? */ if (context.getFlowScope().userObj != null) { out.write("not null"); } else { out.write("not not null"); } %&gt; &lt;!-- Attempt 3: This works, I get the reference to the Object and it spits out the correct firstName, gives me no control other than spitting out the value. --&gt; &lt;userReference&gt;${userObj}&lt;/userReference&gt; &lt;userReference_firstName&gt;${userObj.firstName}&lt;/userReference_firstName&gt; &lt;/rootnode&gt; </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.
