  1. POJSF 2 custom composite component with f:ajax
    text
    copied!<p>I'm trying to create a custom composite component colorPicker using this jQuery plugin <a href="http://www.eyecon.ro/colorpicker/" rel="nofollow">http://www.eyecon.ro/colorpicker/</a>.</p> <p>I´d like to be able to append a jsf tag <code>f:ajax</code>, and when a color is selected, perform an ajax call to the server. I have been testing this functionality and it all appears to be right, but obviously I missed something, because the listener is never called.</p> <p>This is my component code:</p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:c="http://java.sun.com/jsp/jstl/core" xmlns:composite="http://java.sun.com/jsf/composite"&gt; &lt;composite:interface&gt; &lt;composite:attribute name="label" /&gt; &lt;composite:clientBehavior name="customEvent" event="change" targets="#{cc.clientId}"/&gt; &lt;/composite:interface&gt; &lt;composite:implementation&gt; &lt;h:outputStylesheet library="css" name="colorpicker/colorpicker.css" /&gt; &lt;h:outputStylesheet library="css" name="colorpicker/layout.css" /&gt; &lt;h:outputScript library="js" name="colorpicker/jquery.js" target="head"/&gt; &lt;h:outputScript library="js" name="colorpicker/colorpicker.js" target="head"/&gt; &lt;h:outputScript library="js" name="colorpicker/eye.js" target="head"/&gt; &lt;h:outputScript library="js" name="colorpicker/utils.js" target="head"/&gt; &lt;h:outputScript library="js" name="colorpicker/layout.js" target="head"/&gt; &lt;h:outputScript library="js" name="colorpicker/hex.js" target="head"/&gt; &lt;div id="#{cc.clientId}" class="colorSelector"&gt; &lt;div style="background-color: #0000FF;"&gt;&lt;/div&gt; &lt;/div&gt; &lt;script&gt; //jQuery(document).ready(function() { jQuery('##{cc.clientId}').ColorPicker({ color: '#0000ff', onShow: function (colpkr) { jQuery(colpkr).fadeIn(2000); alert('onchange1'); launchEvent(document.getElementById('#{cc.clientId}')); alert('onchange2'); //return false; }, onHide: function (colpkr) { jQuery(colpkr).fadeOut(2000); return false; }, onChange: function (hsb, hex, rgb) { } }); //}); /* &lt;![CDATA[ */ function launchEvent(fieldName) { alert('launchEvent1'); if ("fireEvent" in fieldName) { alert('launchEvent2'); fieldName.fireEvent("onchange"); alert('launchEvent3'); } else { alert('launchEvent4'); var evt = document.createEvent("HTMLEvents"); alert('launchEvent5'); evt.initEvent("change", false, true); alert('launchEvent6'); fieldName.dispatchEvent(evt); alert('launchEvent7'); } /* ]]&gt; */ } &lt;/script&gt; &lt;/composite:implementation&gt; &lt;/html&gt; </code></pre> <p>And this is the page implementation:</p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:f="http://java.sun.com/jsf/core" xmlns:r="http://richfaces.org/rich" xmlns:a="http://richfaces.org/a4j" xmlns:s="http://jboss.org/seam/faces" xmlns:cp="http://java.sun.com/jsf/composite/component"&gt; &lt;h:head&gt; &lt;title&gt;Test&lt;/title&gt; &lt;/h:head&gt; &lt;h:body&gt; &lt;f:view&gt; &lt;h:form prependId="false"&gt; &lt;cp:colorpicker id="colorSelector"&gt; &lt;f:ajax event="customEvent" listener="#{themeBean.changeColor1}" onevent="alert('event raised');"/&gt; &lt;/cp:colorpicker&gt; &lt;h:inputText value="#{themeBean.color1}"&gt;&lt;/h:inputText&gt; &lt;/h:form&gt; &lt;/f:view&gt; &lt;/h:body&gt; &lt;/html&gt; </code></pre>
