Adobe have released an update to LiveCycle Data Services and a new release of BlazeDS. Both have been made available for download and the updated docs have been posted.
New since LiveCycle Data Services 3.0:
Alignment with Flex 4 and Flash Builder 4
The LiveCycle Data Services 3.1 supports the released versions of Flex 4 and Flash Builder 4.
Extensibility and increased flexibility for model-driven development
The ability to generate and customize model-driven application code is much improved in LiveCycle Data Services 3.1. In addition to generating and customizing client-side ActionScript code and model-driven forms, you can generate and customize server-side Java code. You can also extract and customize the code generation templates for the generated client-side and server-side code.
The Modeler provides new user interface features for code generation. You can choose the types of code to generate, which code generation templates to extract, and where to save the generated code and templates.
