In fact talking about this in this thread, I'm wondering if my "Bean"
(aside from probably being a bad label) is actually combining a bit of
a TO and a bit of a BO, and that may not be a good thing. I mean, I
know it works (I've used it), but I also strive to keep my knowledge
in line with the accepted industry standards. After looking at the TO
pattern at Sun's web site, I'm getting the impression that my concept
of a Bean doesn't match up very well with the patterns they list.
Just as an example, this is an example of how I might process,
validate, and persist some form data in a Fusebox 4.1 application.
This would use a TO and a BO and eliminate my "in-between-Bean", and
the BO would validate it's data from the passed TO. Anyone care to
comment on it? Barney, is this getting closer to the nomenclature that
you're familiar with?
<fuseaction name="storeContact">
<invoke object="application.TOFactory"
methodcall="newTO( 'contact', attributes )"
returnVariable="contactTO" />
<invoke object="application.BOFactory"
methodcall="newBO( 'contact', contactTO )"
returnVariable="contact" />
<if condition="#contact.validate()#">
<true>
<invoke object="application.contactManager"
methodcall="save( contact )" />
<do action="success" />
</true>
<false>
<invoke object="contact"
methodcall="getErrors"
returnVariable="errorTO" />
<do action="showContactForm" />
</false>
</if>
</fuseaction>
