  1. POHow do I nest dynamic tables in wicket?
    text
    copied!<p>I'm using wicket to display a list of tables. The number of tables, and the number of rows in each table, are both dynamic.</p> <p>I'm trying to keep it simple and use a RepeatingView for each, and nest them, but wicket says:</p> <blockquote> <p>java.lang.IllegalArgumentException: A child with id 'table' already exists</p> </blockquote> <p>Here is my Java:</p> <pre><code> RepeatingView view = new RepeatingView("listoftables"); for (CCSubscription sub: getCustomer().getSubscriptions()) { //resource balance table ResourceBalance[] resBals = sub.getResourceBalances(); if(resBals!=null &amp;&amp; resBals.length&gt;0) { ListView&lt;ResourceBalance&gt; resBalTable = new ListView&lt;ResourceBalance&gt;("table", Arrays.asList(resBals)) { @Override protected void populateItem(ListItem&lt;ResourceBalance&gt; item) { ResourceBalance bal = item.getModelObject(); item.add(new Label("resource", bal.getResource().getName())); item.add(new Label("balance", bal.getBalance())); } }; view.add(resBalTable); } //end if sub has non-null resource balance } //end loop through subscriptions add(view); </code></pre> <p>And my html is :</p> <pre><code>&lt;ul&gt; &lt;li wicket:id="listoftables"&gt; &lt;fieldset&gt; &lt;legend&gt;&lt;b&gt;Resource Balances&lt;/b&gt; &lt;/legend&gt; &lt;table class="dataview" style="width:50%"&gt; &lt;thead&gt; &lt;tr class="headers"&gt; &lt;th&gt;Resource&lt;/th&gt; &lt;th&gt;Balance&lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;tr wicket:id="table"&gt; &lt;td&gt; &lt;span wicket:id="resource"&gt;&lt;/span&gt; &lt;/td&gt; &lt;td&gt; &lt;span wicket:id="balance"&gt;&lt;/span&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/fieldset&gt; &lt;br/&gt; </code></pre> <p></li> </p> <p>I concede that I'm probably going about this the wrong way, but I can't see what the right way should be.</p> <p>Hope someone can help!?</p>
