[Moose-dev] migrating mondrian to roassal - MOLineShape>>frompositions & view domain

I have just downloaded Moose47 and am starting to migrate my app from Mondrian to Roassal. For the code below where 'a mondrian' /becomes/ 'a roassal' ... At "#1" I get MNU ROLine>>fromPositions For now I worked around this by deleting #fromPositions: and #toPositions: but how do I get similar functionality to manage where the endpoints ? I did find in "attachPoint := ROShorterDistanceAttachPoint instance" in ROLine>>initialize but it would be good to get an idea of the overall architecture for this. At "#2" I get MNU ROMondrianViewBuilder>>domain - where #domain returns an OrderedList of all the model entities, of which I ask each for all its relationship links to other model entities to define the edges. For now I worked around this by factoring "EpcimRoot withAllSubclasses" out to a temporary variable, but I am wondering how in future to access the model entities of the graph. I did find "#elementsWithModelDo:" in ROMondrianViewBuilder>>rawEdgesFrom:to: but not sure whether that is a public/private method. ---------------------- a mondrian title: 'Class Definition - Full Model' ; painting: [ :view :selection | view shape label. view interaction popupText: [ : element | element class comment ]. view nodes: (EpcimRoot withAllSubclasses). view edgesFrom: #superclass.
