From 6bd1704c42f564980677682e1d47e91129d94e5c Mon Sep 17 00:00:00 2001 From: Andrew den Exter Date: Thu, 1 Sep 2011 18:06:11 +1000 Subject: Add support for filtering VisualDataModels. Add a VisualDataGroup element which items within a VisualDataModel can be assigned to. Setting the group property of a VisualDataModel or one of its parts models will filter the items visible within a view to just items belonging to that group. By default all items belong to an 'items' group. The VisualDataModel attached object includes properties indicating whether a item is a member of a group and its index in the group.
