    <p>Using OpenRasta and given the following 2 handlers:</p> <pre><code>public class HelloWorldHandler1 { public string GetHelloWorld(string test, string test2) { return "Hello.World!"; } } public class HelloWorldHandler2 { public string GetHelloWorld(string test) { return "Hello.World!"; } } </code></pre> <p>Configured as follows</p> <pre><code>ResourceSpace.Has.ResourcesOfType&lt;Resource1&gt;() .AtUri("/{test}/{test2}") .HandledBy&lt;HelloWorldHandler1&gt;(); ResourceSpace.Has.ResourcesOfType&lt;Resource2&gt;() .AtUri("/Hello/{test}") .HandledBy&lt;HelloWorldHandler2&gt;(); </code></pre> <p>If I GET <code>/first/example</code> then <code>HelloWorldHandler1.GetHelloWorld</code> is called with parameters <code>first</code> and <code>example</code> as expected.</p> <p>If I GET <code>/Hello/example</code> then <code>HelloWorldHandler2.GetHelloWorld</code> is called with parameter <code>Hello</code> when I would expect it to be called with <code>example</code>.</p> <p><strong>Workaround 1</strong></p> <p>If I reverse the order of the configuration:</p> <pre><code>ResourceSpace.Has.ResourcesOfType&lt;Resource2&gt;() .AtUri("/Hello/{test}") .HandledBy&lt;HelloWorldHandler2&gt;(); ResourceSpace.Has.ResourcesOfType&lt;Resource1&gt;() .AtUri("/{test}/{test2}") .HandledBy&lt;HelloWorldHandler1&gt;(); </code></pre> <p>Then the behavior is as expected:</p> <pre><code>GET /first/example =&gt; HelloWorldHandler1.GetHelloWorld["first","example"] GET /Hello/example =&gt; HelloWorldHandler2.GetHelloWorld["example"] </code></pre> <p><strong>Workaround 2</strong></p> <p>If you change the name of parameter:</p> <pre><code>ResourceSpace.Has.ResourcesOfType&lt;Resource2&gt;() .AtUri("/Hello/{somethingelse}") .HandledBy&lt;HelloWorldHandler2&gt;(); public class HelloWorldHandler2 { public string GetHelloWorld(string somethingelse) { return "Hello.World!"; } } </code></pre> <p>Then the behavior is also as expected.</p> <p><strong>Question</strong></p> <ol> <li>Is it wrong to try to configure URIs in this way? Where they are potentially ambiguous as to which handler should be called?</li> <li>Is this a bug in OpenRasta?</li> </ol>

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.
