Piotr (and anyone else interested): Adobe has its winter break next week but I am leaving earlier (tomorrow) and will be back working on the project in January.
I have created a temporary branch, CollectionData, with my work in-progress. While this branch is incomplete, you might be interested in looking into it. Here's a summary: I created ICollectionView (Collections project), an interface that allows for inserting, removing items from a collection. ArrayList implements it. The idea is that you might want to create a collection that's a subset or a change to data without destroying or modifying the original data. For example, maybe you want to filter the original data or sort it. I created TreeData (Collections project), which implements ICollectionView. TreeData takes in HierarchicalData and converts it to a FlattenedList (extends ArrayList). TreeData implements ICollectionView via its internal flattened list. I created SingleSelectionCollectionViewModel (Basic project) that mimics ArrayListSelectionModel, but assumes its dataProvider is ICollectionView. I created DataItemRendererFactoryForCollectionView (Basic project) which assumes the dataProvider from the model is ICollectionView. This is identical to DynamicItemsRendererFactoryForArrayList so perhaps it will replace that class. I changed TreeModel is use TreeData as its dataProvider property. I changed Tree to accept TreeData as its dataProvider (passes it to its model). You can run a List using SingleSelectionCollectionModel and DataItemRendererFactoryForCollectionView. The Tree works as does DataGrid. I'm in the middle of getting TreeGrid to work with these new classes. Have a wonderful New Year. Regards, Peter Ent Adobe Systems/Apache Royale Project
