Note:
Object Groups
An object group is a logical container for a set of Forms Builder objects.
You need to define an object group when you want to package related objects for copying or
subclassing in another module or if you want to bundle numerous objects into higher-level building
blocks that you can use again in another application. You can package the various objects in an
object group and copy the entire bundle in one operation.
