NullPointer exception configuring a component using a qualified XML element
---------------------------------------------------------------------------

                 Key: JBSEAM-4105
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-4105
             Project: Seam
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.1.2.CR1
            Reporter: Dan Allen
            Assignee: Dan Allen
             Fix For: 2.1.2.GA


Consider the case where there is an existing component defined with the @Name annotation. Now, you want to be able to configure that component in XML. If the class name for the component cannot be derived from the name of the component, then Seam throws a NullPointerException.

Case in point. Assume the following component

package com.mydomain.project;

@Name("com.mydomain.project.init")
public class ProjectInit {
    ...
}

Now assume I am configuring it with:

<project:init stage="test"/>

Because the class of the component, com.mydomain.project.ProjectInit, cannot be derived form the component name, com.mydomain.project.init, Seam tries to do something with the class object that leads to a NullPointerException. What should happen is that Seam should recognize it is configuring an existing component and ignore that fact that it cannot resolve the class. That is the intended behavior.
