Hello,

You can use http://www.metacase.com/support/55/manuals/mwb/Mw-6_3_3.html" rel="nofollow - do to iterate over the collection property, and inside each Scene Design graph there you can use http://www.metacase.com/support/55/manuals/mwb/Mw-6_3_2.html" rel="nofollow - foreach to iterate over the objects there:

foreach .Event
{  'Event: ' id newline
   do :scenes
   {  '   Scene graph: ' id newline
      foreach .()
      {  '      ' id ': ' type newline
      }    
   }
}

Better style is to refactor the parts inside Scene Design into a new generator, which you write in the Scene Design graph type. The top-level generator thus has:

foreach .Event {  'Event: ' id newline    do :scenes    {  _Contents()    } }

and in a http://www.metacase.com/support/55/manuals/mwb/Mw-5_3_1.html#Heading1436" rel="nofollow - new Generator Editor in Scene Design:

_Contents()
'Scene graph: ' id newline
foreach .()
{  '      ' id ': ' type newline
}

It's important to save generators in the right graph type. When http://www.metacase.com/support/55/manuals/mwb/Mw-6_3_12.html" rel="nofollow - calling a sub-generator , it is looked up in the generators of the current graph's type. The current graph changes when you navigate into a different graph, as you do here inside do :scenes {_Contents()}. The sub-generator _Contents() will thus be looked up in the generators of the Scene Design graph type.
