@Factory method not called
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]}
