JSF Composite Component causes EL expression exception in binding attribute - Target Unreachable, identifier 'cc' resolved to null [SWF-1710]

Jura Stuchlik opened SWF-1710 and commented

Using SWF with myfaces and compose binding attribute in composite component – like this:

<?xml version="1.0" encoding="UTF-8"?>
<ui:component xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://xmlns.jcp.org/jsf/core" xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
  xmlns:cc="http://xmlns.jcp.org/jsf/composite" xmlns:h="http://xmlns.jcp.org/jsf/html">

  <cc:interface name="inputText" componentType="inputText">
    <cc:attribute name="value" type="java.lang.Object" required="true" />
    <cc:editableValueHolder name="inputText" targets="inputText" />
  </cc:interface>

  <cc:implementation>
    <div id="#{cc.clientId}" >
        
        <h:inputText id="inputText" binding="#{cc.inputComponent}" value="#{cc.attrs.value}">
          <cc:insertChildren />
        </h:inputText>
    </div>
  </cc:implementation>
</ui:component>

Then error occurs:

Caused by: javax.el.PropertyNotFoundException: Target Unreachable, identifier 'cc' resolved to null
      at org.apache.el.parser.AstValue.getTarget(AstValue.java:74)
      at org.apache.el.parser.AstValue.setValue(AstValue.java:196)
      at org.apache.el.ValueExpressionImpl.setValue(ValueExpressionImpl.java:257)
      at org.apache.myfaces.view.facelets.el.ContextAwareTagValueExpression.setValue(ContextAwareTagValueExpression.java:153)
      ... 104 common frames omitted

Configuration:

• Spring 4.x
• Spring Webflow 2.4.x
• JSF 2.x
• MyFaces 2.2.12

It is like error with mojarra JSF implementation - #829

Basic project for SWF with configured JSF implementation MyFaces and simple composite component with binding attribute. Project generates exceptions on refresh page or send form.

Hi, this issue bothers me too. Is there any progress? Thank you

Indeed the stack trace looks just like #829 which was fixed in 2.4.1 for Mojarra. If anyone is willing to identify the equivalent of this code for a fix in MyFaces I will consider applying it.
