             Summary: [demo app] exception with Nth arg trying to obtain 
previous args
                 Key: CAUSEWAY-3462
                 URL: https://issues.apache.org/jira/browse/CAUSEWAY-3462
             Project: Causeway
          Issue Type: Bug
          Components: Core, Viewer Wicket
    Affects Versions: 2.0.0-RC1
            Reporter: Daniel Keir Haywood
             Fix For: 2.0.0-RC2


in the demo app, use Action > validate

In the middle section, use "selectTvCharactersByTvShowAndSexUsingName" action.
 * enter a TV show for the first param
 * enter a sex for the second param
 * enter a TV character for the 3rd param

This will trigger an exception ... the framework expects this to have only a 
single parameter and passes in the TvCharacter as the first param.

NB: the same functionality implemented using a Paramters object works fine, and 
is perhaps the recommended approach.  Even so, in v1 it used to work this way, 
so we need to preserve this behaviour.
