Body
<p>In a Tapestry component template, is there a simple way to render some markup X times, where X is a parameter of the component?</p> <p>All I can find in the Tapestry docs is the Loop component:</p> <pre class="lang-html prettyprint-override"><code><table class="navigation" xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd"> <tr> <t:loop source="pageNames" value="pageName"> <td class="${tabClass}"> <t:pagelink page="pageName">${pageName}</t:pagelink> </td> </t:loop> </tr> </table> </code></pre> <p>But this is overkill if I just want to render something X times, without needing to pass any parameters. For this usecase I'd really expect something like (pseudo-code):</p> <pre class="lang-html prettyprint-override"><code><table class="navigation" xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd"> <tr> <t:loop times="${x}">  </t:loop> </tr> </table> </code></pre> <p>But nothing like this seems to exist - or does it?</p> <p>For now my workaround is to provide a stub implementation of List which gives size X, and use that as my Loop source:</p> <p>Class:</p> <pre class="lang-java prettyprint-override"><code>private int x; public List<Object> getX() { return new AbstractList<Object>() { public Object get(int arg0) { return null; } public int size() { return x; } }; } </code></pre> <p>Template:</p> <pre class="lang-html prettyprint-override"><code><t:loop source="x">  </t:loop> </code></pre> <p>But this is very ugly - surely there's a nicer way to do something so straightforward?</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.
