    <p>I have never tried what you are doing, so I am not sure the best way to accomplish it. The way you are using the Loc Param, you are extracting a variable from a URL pattern. In your case, <code>http://server/item/ITEMID</code> where <code>ITEMID</code> is the string representation of an Item, and which is the value that gets passed to the <code>fetchItem</code> function. The function call will not have a value if you just arbitrarily call it, and from what I can see you are requesting a value that is not initialized. </p> <p>I would think there are two possible solutions. The first would be to use <a href="http://scala-tools.org/mvnsites/liftweb-2.4/#net.liftweb.http.S" rel="nofollow"><code>S.location</code></a> instead of <code>AnItemPage.menu.currentValue</code>. It will return a <code>Box[Loc[Any]]</code> representing the <code>Loc</code> that is currently being accessed (with the parameters set). You can use that <code>Loc</code> to retrive <code>currentValue</code> and set your parameter. </p> <p>The other option would be to instantiate the actor in your snippet. Something like this: </p> <p><strong>item.html</strong></p> <pre><code> &lt;div data-lift="AnItemPage"&gt; &lt;div id="mycomet"&gt;&lt;/div&gt; &lt;/div&gt; </code></pre> <p>And then in your AnItemPage snippet, something like this:</p> <pre><code>class AnItemPage(item: Item) { def render = "#mycomet" #&gt; new AddCometItemPage(item).render } </code></pre> <p>I haven't tested either of those, so they'll probably need some tweaking. Hopefully it will give you a general idea. </p>

    1. COThanks jcern. I've tried the second idea above but unfortunately I cannot pass an Item object to the snippet. I'll test out your first suggestion now.

    2. COI'm not sure I understand why can't you pass an Item to the snippet? Generally, that would be handled by lift. Lift will look for a snippet with a constructor that accepts the object extracted from the URL. The full code to the example I think you were modeling after is available here for reference: https://github.com/dpp/simply_lift/tree/master/samples/shopwithme/src/main/webapp which has a full example of it.

    3. COPassing the item to the snippet works. I think my initial problem was that I didn't register the menu with SiteMap. Thanks.

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.
