[Seaside] expanded view of MAToOneRelationDescription

[Ch Lamprecht]

Hello,

playing with Magritte - and with Ramons Blog example
http://onsmalltalk.com/programming/smalltalk/screencast-how-to-build-a-blog-in-15-minutes-with-seaside/
(thanks a lot for that), I have the following problem:
Say I would like to add an instance variable datetime to BlogPost (just an 
example - could be any 'composite'). Datetime would hold 'time' and 'date' 
attributes and have appropriate descriptions for that on its class side. If I 
then add a 'descriptionDatetime' to BlogPost class like:

	^(MAToOneRelationDescription
             selector: #datetime
                label: 'datetime'
             priority: 20)
		beRequired;
		yourself

I get a delete and an edit button if I show it like so:
  BlogPost new asComponent.
Works fine...
What would I have to do in order to get an 'expanded' view of my datetime 
instance?? The only way I found was proxying the accessors and descriptions into 
the BlogPost Class...

Thank you, Christoph
