Here is a link forwarded to me by a colleague. This link is a great source of information dealing with LiveCycle Data Services or LCDS. It talks about the product itself and the upcoming release details.
When I browsed this site, I thought it was a very useful link that focuses on a wide range of technical products and topics. Hope this helps you as well.

Hi, I am very new to Adobe Flex, and I’m teaching myself the basics of version 3. I created a dashboard application which uses an HTTPService call to retrieve an external XML file in “e4x” format, to populate a Datagrid object. As you know, this is a straightforward procedure, but I encountered some wacky behavior when one record in the XML file contained a field without a value. In particular, the empty field was that being filtered by the first column in the Datagrid. When the dashboard loads, some error messages appear, related to null object or null values. I then populated that field with a value, ran the program, and the errors vanished. Interestingly, there were records with empty fields, but they did NOT cause a problem. In those cases, however, the empty fields were not associated with the first column in the Datagrid. Thus, the only problem occurred when the empty field was for the first column in the Datagrid.
Have you ever heard of something like this? Does this seem like expected behavior? Any input is helpful, as I’m quite inexperienced with this stuff.
Regards,
Daniel
It looks like the datagrid is using the first column to sort the data, in which case none of the objects can be null. The datagrid uses the first column as the primary column which requires all the objects in that column to have a value.
HTHs.
