  1. POProblem binding a bean property to an element in JSF
    text
    copied!<p>I have an input (JSF) that should be bound to a property in my bean. This property represents another bean and has an auxiliar method that checks if it's null (I use this method a lot).</p> <p>The problem is that the binding is failing to get the proper getter and setter. Instead of reading the method that returns the bean, it reads the one that return a boolean value.</p> <p>The property name is <strong>guest</strong>. The methods are:</p> <ul> <li>getGuest;</li> <li>setGuest;</li> <li>isGuest (checks if guest is null).</li> </ul> <p>JSF is trying to bind the object to <em>isGuest</em> and <em>setGuest</em>, instead of <em>getGuest</em> and <em>setGuest</em>.</p> <p>I cannot rename <em>isGuest</em> to <em>guestIsNull</em> or something, because that would'nt make to much sense (see the class below).</p> <p>Finally, my question is: <strong>how can I bind this property to the object without renaming my methods? Is it possible?</strong></p> <p>I also accept suggestions of a better method name (but the meaning must be the same).</p> <hr> <p><strong>Entity</strong></p> <pre><code>@Entity public class Passenger { private Employee employee; private Guest guest; public Passenger() { } @Transient public boolean isEmployee() { return null != this.employee; } @Transient public boolean isGuest() { return null != this.guest; } @OneToOne public Employee getEmployee() { return this.employee; } public void setEmployee(Employee employee) { this.employee = employee; } @OneToOne public Guest getGuest() { return this.guest; } public void setGuest(Guest guest) { this.guest = guest; } } </code></pre> <p><strong>JSF</strong></p> <pre><code>&lt;h:inputText value="#{passenger.employee}" /&gt; &lt;h:inputText value="#{passenger.guest}" /&gt; </code></pre>
