Hi, I don't know how I can save a lot of content that can be modified or not.
First, when we load all the content from database for a timeline(main object) and transfert all these table to many Objects in flex. [Bindable] TimelineModelLocator dateType presentation from to divisions (arraycollection with object) autors (arraycollection with object) layerData (arraycollection with object) categoryData (arraycollection with object) entryData (arraycollection with object) ... The user can modify all content, remove items, add items. When the user click "save all", what is the best to do? Remove all what was in the database and save the new content in all tables. Loop in all object and compare a checksum to know what have been modify/added/deleted... Other idea??
