copied!<p>You need to ensure that your custom component class extends <a href="http://download.oracle.com/javaee/6/api/javax/faces/component/UIInput.html" rel="nofollow noreferrer"><code>UIInput</code></a> and that you're in the <a href="http://download.oracle.com/javaee/6/api/javax/faces/render/Renderer.html#encodeEnd%28javax.faces.context.FacesContext,%20javax.faces.component.UIComponent%29" rel="nofollow noreferrer"><code>encodeEnd()</code></a> method of your renderer writing the component's client ID as <code>name</code> attribute of the HTML input element. Then you can in the overriden <a href="http://download.oracle.com/javaee/6/api/javax/faces/render/Renderer.html#decode%28javax.faces.context.FacesContext,%20javax.faces.component.UIComponent%29" rel="nofollow noreferrer"><code>decode()</code></a> method of your renderer just grab the submitted value from the request parameter map with the component's client ID as parameter name and set it as <a href="http://download.oracle.com/javaee/6/api/javax/faces/component/UIInput.html#setSubmittedValue%28java.lang.Object%29" rel="nofollow noreferrer"><code>UIInput#setSubmittedValue()</code></a> and let JSF do the remnant of the job of converting, validating and updating the model value.</p> <pre><code>@Override public void decode(FacesContext context, UIComponent component) { // Do if necessary first validation on disabled="true" or readonly="true", if any. // Then just get the submitted value by client ID as name. String clientId = component.getClientId(context); String submittedValue = context.getExternalContext().getRequestParameterMap().get(clientId); ((UIInput) component).setSubmittedValue(submittedValue); } </code></pre> <hr> <p><strong>Unrelated</strong> to the concrete problem, are you aware of the new composite component support in JSP's successor Facelets? I have the impression that you don't necessarily need a custom component for this purpose. Or are you really restricted to using the legacy JSP as view technology in spite of that you're already on JSF 2.x?
