    TreeStateAdvisor is never created as component in Seam

      Hi,

      I have takes the example from richfaces demo, the one with TreeStateAdvisor. I have just changed the name to OrganizationUnitTreeStateAdvisor and added Seam @Name annotation.

      For some reason this component is never created - at least this is what log on the console is showing.

      Any ideas why?

      /p

          Well I know why:

          richfaces-impl-3.1.1* was not in the lib dir of ear that is containing my implementation of TreeStateAdisor.

          Now I have another problem which I believe is more JBoss AS related:

          ehh... 'Why it never gets any easier?!' ;-)

            Guess what: all the jar's from WEB-INF/lib should go to ear's lib dir.

            Now works.

            BTW. upgraded to richfaces-3.1.2 - still works.

              Another solution is to move the TreeStateAdvisor implementations into the web module, which makes sense considering they are only useful to the UI. (Seam will still deploy them as POJO components.)

                Okay, still a bit of a Seam n00b, but I'm not sure what "into the web module" means.  With the standard Seam shell that gets created, I don't have a directory structure that gets compiled down and put into WEB-INF/classes.

                 

                Should I assume this means create a separate project for all my UI components, compile that down into a JAR file and then put that in WEB-INF/lib for the Seam EAR?
