    <p>i've wicket panel with list of ProductViews (as SELECT)<br/> <img src="https://i.stack.imgur.com/ojI2s.png" alt="product list by categories"> <br /> after you choose your ProductView from SELECT, its load Product from database by id of ProductView into details form. You can modify Product entity and you can save it when you finish.<br/><img src="https://i.stack.imgur.com/74350.png" alt="details form"> <br/> After save i try to refresh SELECT list to update its data, but it doesn't work(i mean, for example, SELECT contains an old name of product after rename it, but when i select the same ProductView, it reload an entity into details form again, and of course the new data appears from database) i don't want to reload product list again, i want to solve it from memory. Here is my source: </p> <p>ProductView:</p> <pre><code>@Entity @Table(name = "product") @XmlRootElement public class ProductView implements Serializable{ private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Basic(optional = false) @Column(name = "id") private Long id; @Column(name = "name") private String name; @Enumerated(EnumType.ORDINAL) @Column(name = "category") private Category category; public ProductView() { } public ProductView(Long id) { this.id = id; } public ProductView(Product product) { this.id = product.getId(); this.name = product.getName(); this.category = product.getCategory(); } // + getters &amp; setters } </code></pre> <p>Product:</p> <pre><code>@Entity @Table(name = "product") @XmlRootElement public class Product implements Serializable { // same as ProductView but more data, objects, connections, etc } </code></pre> <p>And wicket panel with comments</p> <pre><code>private Product product;

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
