<p>Have a look at this similar <a href="https://stackoverflow.com/questions/4429208/bind-objects-in-a-set-collection">stackoverflow question</a>: </p> <p>According to the answer the best way would be to set the collection as a list</p> <pre><code><form:input path="contacts[0].phoneNumber"/> </code></pre> <p>or as a map:</p> <pre><code><form:input path="contacts['contactId'].phoneNumber"/> </code></pre> <p>You can use a lazy list (<a href="http://static.springsource.org/spring/docs/2.0.x/api/org/springframework/util/AutoPopulatingList.html" rel="nofollow noreferrer">Spring Autopopulating List</a>, <a href="http://commons.apache.org/collections/api/org/apache/commons/collections/ListUtils.html#lazyList%28java.util.List,%20org.apache.commons.collections.Factory%29" rel="nofollow noreferrer">Apache Commons Lazy List</a>, <a href="http://guava-libraries.googlecode.com/svn/trunk/javadoc/com/google/common/collect/Lists.html#transform%28java.util.List,%20com.google.common.base.Function%29" rel="nofollow noreferrer">Guava lists</a>) or a lazy map (<a href="http://guava-libraries.googlecode.com/svn/trunk/javadoc/com/google/common/collect/MapMaker.html" rel="nofollow noreferrer">Guava's Map Maker</a>, <a href="http://commons.apache.org/collections/api-release/org/apache/commons/collections/MapUtils.html#lazyMap%28java.util.Map%2C%20org.apache.commons.collections.Transformer%29" rel="nofollow noreferrer">Apache Commons lazy map</a>) so you won't have to worry to create a new object when you need them in the list or map. Just when you do a get to a position which have not been initialized the list/map wll automatically create a new instance of the object.</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.
