The Dynamics feature is implemented through the use of the class called
fxListener in the _ReportListener class libary of the FFC directory. When
you "indirectly" use a report listener, such as your first example of OBJECT
TYPE 1, VFP automatically uses this listener to run the report. In your
second example, you are instantiating the UpdateListener class which does
not have the code to implement the Dynamics feature.

In SP2, fxListener was introduced in the hierarchy between the
_ReportListener and the UtilityListener class (Use the class browser to see
the new hierarchy). As long as you create a listener based on fxListener or
something farther down the hierarchy, the Dynamics will work. In SP2, the
UpdateListener class is only included for backward compatibiliity and all
it's features have been moved into the other classes in the class libarary.

Keep your eyes out for a new book to be released soon ... "Making Sense of
Sedna and SP2". There are three chapters in the book that dive into all the
changes and new features added to the Report Writer in SP2. Dynamics is just
the tip of the iceberg on what you can do with the new Advanced features.
