    <p>I have a list of records (Trades) that I need to display onto a JSP Page as tabular data from the Trade POJO and need to get checkbox selections of some of these records as Form POST back to action where I need to check which records were selected. I am doing tabular data display using <strong>c:forEach</strong>. JSP is as :</p> <pre><code>&lt;s:form id="executeTradesForm" name="executeTradesForm" action="ExeTradeAction"&gt; &lt;table id="tradesForDisplayTable" border="1" align="left" width="100%"&gt; &lt;tr&gt; &lt;s:checkbox name="selAllTradeIds" fieldValue="selAllTradeIds"/&gt; &lt;th&gt;Trade ID&lt;/th&gt; &lt;th&gt;Trade Source&lt;/th&gt; &lt;th&gt;Currency&lt;/th&gt; &lt;th&gt;Trade Status&lt;/th&gt; &lt;th&gt;Trade Date&lt;/th&gt; &lt;th&gt;Start Date&lt;/th&gt; &lt;th&gt;Maturity Date&lt;/th&gt; &lt;th&gt;Trader Name&lt;/th&gt; &lt;th&gt;Trade Quantity&lt;/th&gt; &lt;th&gt;Trade Price&lt;/th&gt; &lt;th&gt;Buy / Sell&lt;/th&gt; &lt;/tr&gt; &lt;c:forEach var="trade" items="${tradesList}" varStatus="stat"&gt; &lt;tr&gt; &lt;td&gt;&lt;s:checkbox name="selTradeId" fieldValue="selTradeId"/&gt;&lt;/td&gt; &lt;td&gt;&lt;c:out value="${trade.tradeId}" /&gt;&lt;/td&gt; &lt;td&gt;&lt;c:out value="${trade.tradeSource}" /&gt;&lt;/td&gt; &lt;td&gt;&lt;c:out value="${trade.currency}" /&gt;&lt;/td&gt; &lt;td&gt;&lt;c:out value="${trade.tradeStatus}" /&gt;&lt;/td&gt; &lt;td&gt;&lt;c:out value="${trade.tradeDate}" /&gt;&lt;/td&gt; &lt;td&gt;&lt;c:out value="${trade.startDate}" /&gt;&lt;/td&gt; &lt;td&gt;&lt;c:out value="${trade.maturityDate}" /&gt;&lt;/td&gt; &lt;td&gt;&lt;c:out value="${trade.traderName}" /&gt;&lt;/td&gt; &lt;td&gt;&lt;c:out value="${trade.tradeQuantity}" /&gt;&lt;/td&gt; &lt;td&gt;&lt;c:out value="${trade.tradePrice.value}" /&gt;&lt;/td&gt; &lt;td&gt;&lt;c:out value="${trade.buySell}" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/c:forEach&gt; &lt;s:submit align="left" name="submit" value="Execute Trades" /&gt; </code></pre> <p>What is the best approach here in terms of using <strong>s:checkbox</strong> or something else like <strong>s:checkboxlist</strong> . </p> <p>I need to know if when using <strong>s:checkbox</strong> can we have <strong>fieldValue</strong> attribute as something dynamic like '<strong>checkbox-</strong>' (tradeId being unique and coming from trade.tradeId. How to get that dynamic attribute?</p> <p>Assuming tradeId is a string value like TRD12345, what will the Action class store it as ? String[] or boolean array ? (when we use s:checkbox)</p> <p><em>Struts2 docs is wanting and has not given enough examples of using s:checkbox with collections etc.</em></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.
