[jboss-user] [JBoss Seam] - can i do this...

[c_eric_ray]

I know I can use @DataModel but I want try the following and it seems logical to me but it doesn't work.


  | @Name("package")
  | class ... {
  |   @In(create=true) @Out(scope=ScopeType.CONVERSATION)
  |   private List<PackageEntity> packages;
  | }
  | 

then in my web page do this...


  | <h:dataTable value="#{package.packages}" var="pkgEntity" ...
  | 

I thought I could but I keep getting the following exception
