Hi,
Using ASObject I m able to exchange data from .NET to Flex. But I have 2 questions :
1) Will there be any changes required, when migrating to future versions of Flex, as in Flex 2.0, which is going to support .NET? Can we still retain ASObject or should we change them to Custom classes.
2)Does this hold good even for Java? i.e Do I have to use ASObject to exchange data from Java to Flex, or is it possible to pass custom classes itself from Java to Flex.
Regards
Priyanka

ASObject title = new ASObject();
