PObinding objects initialization in JSF

Body
copied!<p>I have this bean in application scope. </p> <pre><code>public class User { private UICommand link; private String name; public User(){ System.out.println("User.User()"); name = "Test Link"; } public UICommand getLink() { System.out.println("User.getLink()"); System.out.println(link==null?"link is null":"link is not null"); return link; } public void setLink(UICommand link) { System.out.println("User.setLink()"); this.link = link; System.out.println("link: "+link.toString()); } public void change(){ System.out.println("User.change()"); } //setter and getter for name } </code></pre> <p>I have this jsf on jsp page.</p> <pre><code><f:view> <h:form> <h:commandLink binding="#{user.link}" action="#{user.change}" value="#{user.name}"/> </h:form> </f:view> </code></pre> <p>I thought that the UICommand object would be reused (by sending the serialized state of the object along with the HTML output) and thus maintain the state and binding. But I get this sysoutput.</p> <pre><code>//When page loads User.User() User.getLink() link is null User.setLink() link: javax.faces.component.html.HtmlCommandLink@14e4ce7 //when user clicks the link User.setLink() link: javax.faces.component.html.HtmlCommandLink@6fcc9c User.change() </code></pre> <p><code>UICommand</code> object is different each time the user clicks the link!!! Also i believe <code>getLink()</code> runs only once when that object is first loaded on page but if that's the case then the page woudn't reflect the latest UICommand object!</p>
