[jboss-user] [JBoss Seam] - Re: Possible component.xml problem in 1.1.0 CR2

[quilleashm]

Ok thanks.  I've played around more and got a bit further but I think I'm in to work-around territory rather than fixing the problem properly.

Here is my current components.xml


  | <?xml version="1.0" encoding="UTF-8"?>
  | <components xmlns="http://jboss.com/products/seam/components"
  |             xmlns:core="http://jboss.com/products/seam/core"
  |             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  |             xsi:schemaLocation=
  |                 "http://jboss.com/products/seam/core http://jboss.com/products/seam/core-1.1.xsd
  |                  http://jboss.com/products/seam/components http://jboss.com/products/seam/components-1.1.xsd">
  | 
  |   <core:init debug="true"/>
  | 
  |   <!-- adding this makes the NPE go away -->
  |   <core:locale-selector/>
  | 
  |   <core:managed-hibernate-session name="referenceSession"/>
  | 
  |   <core:hibernate-session-factory name="hibernateSessionFactory"/>
  | 
  | </components>
  | 

I added the locale-selector component here explicitly which forces it to load and means my web page serves up properly.  However I still get a couple of other NPEs.

Which are both similar to the locale problem.  I found that the Component.forName(name) (which looks up components in the application context) call in Component.getInstance() is returning null.  It was doing this for the locale-setting until I included it my components.xml but I don't think I should be putting all the core components in my components file.

I will keep investigating but any insight or ideas about why the core components don't seem to be loading automatically would be appreciated.

Thanks.

Mike.
