Hi all, a trick, maybe could help: looking at DataBindingTest (under the tests subproject) you can find that in some places some data is transformed (using Pivot Serializers) to/from json (that as you know has a hierarchical structure, good for trees for example) ... so maybe you could try to save/load a json version somewhere, if appliable to your business case and to your data storage structure/features.
Bye, Sandro
