Need support for hierarchical beanRefFactory in ContextLoader
-------------------------------------------------------------

                 Key: JBSEAM-3639
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-3639
             Project: Seam
          Issue Type: Feature Request
          Components: Spring
    Affects Versions: 2.1.0.GA
            Reporter: Bob Shanahan


The Spring ContextLoaderListener allows loading of shared (by multiple wars), hierarchical contexts as in the following sample web.xml config:

  <context-param>
      <param-name>contextConfigLocation</param-name>		
      <param-value>/WEB-INF/applicationContext.xml</param-value>
   </context-param>
   <context-param>
      <param-name>locatorFactorySelector</param-name>
      <param-value>classpath:com/i2i/services/beanRefFactory.xml</param-value>
   </context-param>
   <context-param>
      <param-name>parentContextKey</param-name>
      <param-value>i2i.services</param-value>
   </context-param>
   <context-param>
      <param-name>webAppRootKey</param-name>
      <param-value>i2i.webt</param-value>
   </context-param>
    
   <listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
   </listener>

The Seam ContextLoader, however, only allows loading of one or more application contexts, neither allowing single instances of shared contexts nor allowing for hierarchical contexts (via setting of parent context key).

Attempts to overcome the limitation with the following <spring:context-loader> config and beanRefFactory.xml fails as only the beans defined in the beanRefFactory are directly visible to Seam.

<spring:context-loader>
    	<spring:config-locations>
    		<value>classpath:com/i2i/services/beanRefFactory.xml</value>
    		<value>/WEB-INF/beanRefFactory.xml</value>
    	</spring:config-locations>
</spring:context-loader>
