Making a Composite Component in JSF2
I have a problem with my composite component in JSF2. I implement a list using ui and li. But if I use my component nothing happens. My list-tag is not replaced in code generated by facelet. So whats wrong with this.
The composite component is stored under /resources/util/list.xhtml. Here is the code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html 开发者_StackOverflow中文版xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:composite="http://java.sun.com/jsf/composite"
xmlns:ui="http://java.sun.com/jsf/facelets">
<head><title>(For validation only)</title></head>
<body>
<composite:interface>
<composite:attribute name="values"/>
<composite:attribute name="listStyle"/>
<composite:attribute name="elementStyle"/>
</composite:interface>
<composite:implementation>
<ul class="#{cc.attrs.listStyle}">
<ui:repeat var="element" value="#{cc.attrs.values}">
<li class="#{cc.attrs.elementStyle}">#{element}</li>
</ui:repeat>
</ul>
</composite:implementation>
</body></html>
I use my tag this way
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<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:core="http://java.sun.com/jsf/core"
xmlns:utils="http://http://java.sun.com/jsf/composite/utils">
<h:head>
<title>Show user Color</title>
<style type="text/css">
.elements { font-style: italic; }
.list { margin: 0px; padding:0px;}
</style>
</h:head>
<h:body>
<h1>Show Color</h1>
<p>User selected: #{ColorBean.selectedColor}</p>
<p>User set hex: #{ColorBean.showHex == true? "yes": "no"}</p>
<p><h:outputFormat value="#{msgs.hexNotification}"
rendered="#{ColorBean.showHex}">
<core:param value='#{ColorBean.showHex == true? "yes": "no"}' />
</h:outputFormat>
</p>
<fieldset><legend>Colors</legend>
<utils:list values="#{ColorBean.colors}" listStyle="list" elementStyle="elements"/>
</fieldset>
</h:body>
</html>
Here is the generated code.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" >
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:utils="http://http://java.sun.com/jsf/composite/utils"><head>
<title>Show user Color</title>
<style type="text/css">
.elements { font-style: italic; }
.list { margin: 0px; padding:0px;}
</style></head><body>
<h1>Show Color</h1>
<p>User selected: green</p>
<p>User set hex: no</p>
<p>
</p>
<fieldset><legend>Colors</legend>
<utils:list values="[Ljava.lang.String;@13e86ec" listStyle="list" elementStyle="elements"></utils:list>
</fieldset><div id="javax_faces_developmentstage_messages"></div></body>
</html>

Change your
