I have a question about data services with data managment enabled in Adobe Flex Builder 4. The issue is moretheoretical thanpractical.
When I need toremove an itemfrom the DataProvider I use the delete method of autogenerated service, but when I need to add or update item in DataProvider, I use methods of DataProvider ArrayCollection directly (addItem ...). When I try to remove item from the DataProvider with removeAt method, no changes made to database after commit. Why and how this stuff works?
P.S. Sorry for my bad English, I use Google transltate.
