[JBoss Seam] - @In attribute requires non-null value: register.user
by springfans
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 value="#{register.verify}": org.jboss.seam.RequiredException: @In attribute requires non-null value: register.user

Caused by: javax.el.ELException: //D:/app/eclipse/framework/PROJECT_SRC/TestWeb/WebRoot/register.xhtml @82,76 value="#{register.verify}": org.jboss.seam.RequiredException: @In attribute requires non-null value: register.user

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