TreeMapLayout - Mondrian - outgoing edges

Hi,

The second challenge I mentioned in the mail before is related to outgoing edges stored for MONodes.

When I create a layout in the following way...

view nodes: self nodes.

view edges: self nodes            

       from: [ :each | each ] 

       toAll: [ :each | each children ].

view layout: (MOTreeMapLayoutIncubation withWeightBlock: [ :e | e model entity numberOfLinesOfCode ]).

...Everything works as expected. Meaning every MONode has outgoing edges to its direct children defined.

However, if I construct a layout in the following way...

view nodes: (self getLevel: 3) "Returns all nodes on a certain level in the tree"

forEach: [ :each |

view nodes: each recursiveChildren. "All nodes below given node"

view edges: each recursiveChildren "From all nodes to all their direct children"

       from: [ :node | node ] 

       toAll: [ :node | node children ].

view layout: (MOTreeMapLayoutIncubation withWeightBlock: [ :e | e model entity numberOfLinesOfCode ]).

].

...So that I have multiple TreeMaps (one for each node on level 3 in the graph), the MONodes do not have outgoing edges defined and thus I can't render the TreeMap.

Does anyone have an idea what could cause this behavior?

Cheers,

Dennis
