Normally, if you have built your aggregates as following
<into CormasModel> self spaceModel setAggregates: Aggregate from:
Cell verifying: [:c | c context = #tree]
You should obtain for the attribut "components" of one of your
Aggregates :
Set (a CormasNS.Models.TSE.Cell a CormasNS.Models.TSE.Cell a...)
If your Aggregates do not belong to an upper entity, the attribut
"theCSE" is empty : Dictionary ()
But you should obtain for the attribut "theCSE" of your
spatialEntityElement (Cell), something like:
Dictionary (#Aggregate->a CormasNS.Models.TSE.Aggregate )
Best regards,
Pierre
