    @In bijected attributes remaining null?

    Gregory Pierce Newbie

      I have a Seam application in which I'm attempting bijection with @In,
      but for some reason the object that is being bijected isn't getting a
      value from the JSF layer. How does one go about debugging this? I can
      see all the tables, components, etc. get created and the JSF page is
      showing up and the call to the controller (action) is happing fine as I
      put in some System.out.printlns to confirm this, but the entity bean
      that is being created simply never gets injected and I'm stumped.

      Can anyone point me towards some things that might be culprits?

            Those are the config files. If there are any files that can be removed, let me know as James and I started just added everything to try and get it to work.
