Hi there,
I got the following problem on my Seam application. Looking at the error, it
seems my properties are not injected by Seam. Thanks beforehand for your help.
The application is to register new user before enabling the user to login to
the system.
When clicking "register" on the registration page, debug page appear with the
following:
Exception during request processing:
javax.faces.FacesException: javax.el.ELException:
//D:/app/eclipse/framework/PROJECT_SRC/TestWeb/WebRoot/register.xhtml @82,76

Caused by: javax.el.ELException:

Looking at the error, it appear to me that there is either EL exception or
injection error (no idea why though....)
