NPE when using the new UEL inside a composite component in Glassfish 3.0.1
--------------------------------------------------------------------------
Key: MYFACES-2826
URL: https://issues.apache.org/jira/browse/MYFACES-2826
Project: MyFaces Core
Issue Type: Bug
Components: JSR-314
Affects Versions: 2.0.1
Environment: glassfish3.0.1
Reporter: Jan-Kees van Andel
When I write a composite component like this one:
<html xmlns="http://www.w3.org/1999/xhtml";
xmlns:f="http://java.sun.com/jsf/core";
xmlns:h="http://java.sun.com/jsf/html";
xmlns:p="http://www.parleys.com/jsf/taglib";
xmlns:composite="http://java.sun.com/jsf/composite";>
<composite:interface>
<composite:attribute name="navigateToPage" type="java.lang.String"/>
</composite:interface>
<composite:implementation>
<h:commandLink id="asdsadsdadasdas"
action="#{testBean.gotoPage(cc.attrs.navigateToPage)}"
value="MyFaces Test">
<composite:insertChildren/>
</h:commandLink>
</composite:implementation>
</html>
And I use it in my page like this:
<parleys:navigationLink2 navigateToPage="channels"/>
I get the following NPE:

I am using Glassfish 3.0.1, with the Sun UEL implementation. It works when I
disable MyFaces and use Mojarra.
