Building intelligent forms using Adobe LiveCycle Designer

XFA 3.0 Specification Available

The recent update to Acrobat/Reader 9.1 supports XFA 3.0. Unfortunately, the currently-shipping version of LiveCycle Designer (even with its update) won’t author/support more than XFA 2.8 until the next release. The comments for the XFA 3.0 spec indicate that “there will be releases [of LiveCycle Form Server and LiveCycle Designer] for XFA 3.1 and they will also handle 3.0.”

There are still some great things worth mentioning about XFA 3.0. In particular,

  • new “inactive” value for the presence attribute which, when set on a container (e.g. subform), “prevents the container and its contents from processing calculations, validations, and events”;
  • enhancements to events framework now permits event propagation upward to parent objects — this is great because you can now implement validation code on a subform for all of its children instead of having validation code in each child, for example;
  • new validation events and global validation handling control — this should address a lot of the current issues with form validation.

It looks like John Brinkman will be detailing these new features, and perhaps others, soon.
