    <p>I've trouble using type conversion in struts 2 to convert collection of bean. I've following action class : </p> <pre><code>@Validation() @Conversion() public class HelloWorldAction extends ActionSupport { private List&lt;HelloBean&gt; helloBeans = new ArrayList&lt;HelloBean&gt;(); public String execute() throws Exception { System.out.println(helloBeans); return SUCCESS; } public List&lt;HelloBean&gt; getHelloBeans() { return helloBeans; } @TypeConversion(rule = ConversionRule.COLLECTION, converter = "foo.HelloBean") public void setHelloBeans(List&lt;HelloBean&gt; helloBeans) { this.helloBeans = helloBeans; } } </code></pre> <p>and my bean class : </p> <pre><code>public class HelloBean { private String name; private Integer age; public String getName() { return name; } public void setName(String name) { this.name = name; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } } </code></pre> <p>and my JSP file : </p> <pre><code>&lt;s:form action="helloWorld"&gt; &lt;s:textfield name="helloBeans.name" label="name1"/&gt; &lt;s:textfield name="helloBeans.name" label="name2" /&gt; &lt;s:textfield name="helloBeans.age" label="age1"/&gt; &lt;s:textfield name="helloBeans.age" label="age2"/&gt; &lt;s:submit /&gt; &lt;/s:form&gt; </code></pre> <p>When process has been submitted, struts always give me 4 object, instead of 2 object inside collection. I know other workaround using index in property will solve problem, but for my case i need collection to be dynamic. Is there way to solve this kind of issue ?</p> <p>I've tried others annotation as well : </p> <pre><code>@Element(value =foo.HelloBean.class ) @CreateIfNull( value = true ) @KeyProperty( value = "name" ) private List&lt;HelloBean&gt; helloBeans = new ArrayList&lt;HelloBean&gt;(); </code></pre> <p>but none of these worked</p>

    1. COFYI: You don't need to initialize helloBeans in your action. Your setter will do that.

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.
