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
