Hi all,
I'm currently setting up Seam in an already working JSF based project. There is a hack
that I wrote to call an action to init a bean when invoking a JSF page from a non-JSF
servlet. I'm trying to replace it by a @Factory method but I'm really struggling
here.
I'm running JSF on Resin web server using MyFaces implementation. I followed the setup
instructions at chapter 21 of Seam documentation
(http://docs.jboss.com/seam/1.2.1.GA/reference/en/html/configuration.html) and the bean is
super simple, heavily inspired by the example found at:
http://java.sys-con.com/read/180363.htm
Now my problem is that the @Factory method is never called and the server fails badly,
giving me a blank page and throwing an ugly exception on the console:
| javax.servlet.ServletException: Could not retrieve value of component with path :
{Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId:
/faces/dataview/news.jsp][Class: javax.faces.component.html.HtmlOutputText,Id: date]}
