Body
<p>AFAIK you must use:</p> <pre><code> <s:form action="hello-world"> <s:textfield name="helloBeans[1].name" label="name1"/> <s:textfield name="helloBeans[1].age" label="age1"/> <s:textfield name="helloBeans[2].name" label="name2" /> <s:textfield name="helloBeans[2].age" label="age2"/> <s:submit /> </s:form> </code></pre> <p>I think the biggest issue is not that it must be done this way but that you think that this means it can not be dynamic, consider that the text fields are rendered more-less (actually less because I removed the 'id' and 'value' attributes):</p> <pre><code><input type="text" name="helloBeans[1].name"/> <input type="text" name="helloBeans[1].age"/> ... </code></pre> <p>There is no reason you simply can not either handle this in your jsp dynamically as done to test the view:</p> <pre><code> <h1>Display HelloBeans</h1> <table> <s:iterator value="helloBeans"> <tr> <td><s:property value="name"/></td> <td><s:property value="age"/></td> </tr> </s:iterator> </table> </code></pre> <p>Or if your issue is client side then use JavaScript (or better a JS library such as jQuery) to add new text fields to the DOM... and use string concatenation to build the correct OGNL for the 'name' attributes.</p> <p>Note if your dynamic behavior is server side in the JSP then</p> <pre><code><s:property value="#helloBeans.index" /> </code></pre> <p>will get you the index of the current iteration when used inside the s:iterator tag.</p>

Guidance

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.
