Hi, all! I have OrderedCollection of Dictionaries and I want to display content of each Dictionary using TreeModel. I wrote these code, but it doesn't work correctly. And I get some errors. mt := TreeModel new. mt roots: (collectionFirst select: OrderedCollection new); childrenBlock: [ :item | item ]. mt openWithSpec. (This is screenshot of my work) <http://forum.world.st/file/n4876653/ScreenPharoTreeModel.png> I need to show each pair of Dictionary in new node. Can you help me, please? -- View this message in context: http://forum.world.st/How-to-display-Dictionary-using-TreeModel-tp4876653.ht...
