The mapper framework I have is actually not tied to JavaBeans, or only by
default. It abstracts into separate classes the roles of getting fields,
setting fields, and creating objects. In other words, I have abstract
classes called Getter, Setter, and Creator. You can specify any
implementation in order to override the default ones which are based on
PropertyUtils.
The reason I made it this way is because I had in mind a larger scope of
application: you can use it also to get and set fields from ResultSet and
PreparedStatement, or anything you want provided you can make a Getter,
Setter, and if necessary a Creator. We even have used it for getting fields
out of an Iterator.

Subject: Re: Struts 1.1 TODO List -- Event and Listener Model
A comment I just made on the new thread about "Extending the scope of the
struts
validation", really belongs here on this thread... My problem with tying
forms
to JavaBeans is that JavaBeans don't seem to be flexible enough to use for
dynamic forms. If I need to create a form or modify it at runtime, how do I
do
it using a JavaBean? How do I add properties to a JavaBean dynamically? If
dynamic forms are going to require more than just a JavaBean, then the
validation framework can't be tied to just JavaBeans.
