A module has a tree consisting of folders and sub-folders, which contain items.
I'm using Flex 3.
The user would like to have the data saved automatically. That is, whenever the user creates a sub-folder, drags and drops items, deletes items or sub-folders, and the like, the XML data behind the tree is saved automatically after each manipulation to the database. The user does not have to click on the Save button after manipulating the tree.
How do I go about implementing the automatic save? Do I need to use LiveCycle Data Services or something else? What are my options?
