[jboss-user] [JBoss Seam] - Re: javax.faces.el.PropertyNotFoundException: Base is null

[asookazian]

I added a commandButton to the addGadget.jsp and the associated new method to the SLSB and got the following:

  | 2007-08-28 00:34:42,875 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/PracticalSeam-Intro-Seam].[Faces Servlet]] Servlet.service() for servlet Faces Servlet threw exception
  | javax.faces.FacesException: Value binding '#{gadget.gadgetTypes}'of UISelectItems with component-path {Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId: /addGadget.jsp][Class: javax.faces.component.html.HtmlForm,Id: _idJsp0][Class: javax.faces.component.html.HtmlSelectOneMenu,Id: _idJsp2][Class: javax.faces.component.UISelectItems,Id: _idJsp3]} does not reference an Object of type SelectItem, SelectItem[], Collection or Map but of type : null

something wrong with the classpath or configuration(s)?  this is project based on the intro-Seam example from the new Practical Jboss book...
