    <p>I have a form with two halves, one for attaching a wide thumbnail to an asset and one for a standard-size thumbnail. The jsp file generating the page calls thumbnail.tag, which calls thumb.tag twice:</p> <pre><code>&lt;thumbnail:thumb label="75px Thumbnail" /&gt; &lt;thumbnail:thumb label="Wide Thumbnail" /&gt; </code></pre> <p>thumb.tag in turn has the following:</p> <pre><code>&lt;s:if test="#attr.label == '75px Thumbnail'"&gt; &lt;thumbnail:standardThumb /&gt; &lt;/s:if&gt; &lt;s:elseif test="#attr.label == 'Wide Thumbnail'"&gt; &lt;thumbnail:wideThumb /&gt; &lt;/s:elseif&gt; </code></pre> <p>The sole difference between standardThumb.tag and wideThumb.tag is the variable names, e.g. stdThumbUrl and wideThumbUrl. I have been assigned to refactor this into a single file and pass in the "std" or "wide" string. I have found this works just fine with regular HTML tags. For example, added to thumb.tag:</p> <pre><code>&lt;thumbnail:standardThumb tst="standard" /&gt; </code></pre> <p>and to standardThumb.tag:</p> <pre><code>&lt;%@ attribute name="tst" required="true"%&gt; ... &lt;iframe id="${tst}ThumbImage" ... &gt; </code></pre> <p>and this works as expected. I can't seem to find a way to get "standard" into </p> <pre><code>&lt;s:if test="content.standardThumbUrl != null"&gt; </code></pre> <p>in the same file. I've tried every combination of % and $ and # and {} that I can think of, but nothing has worked. Is there some proper syntax that will help me achieve the effect I'm looking for?</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.
