Well, i found that having a separate DAO for the subobject made things a lot
simplier. Going back to a previous thread, i got rid of a lot of stuff that
looked like this (in the query, but also in the form and the post submit
process):
<cfloop ... >
CFQUERY>
INSERT INTO mytable
(course,
degree,
emp_course_id...)
VALUES
(<cfqueryparam cfsqltype="cf_sql_varchar" value="#form["course"&i]#">,
<cfqueryparam cfsqltype="cf_sql_varchar" value="#form["degree"&i]#">,
<cfqueryparam cfsqltype="cf_sql_varchar" value="#form["emp_course_id"&i]#">)
</CFQUERY>
</cfloop>
And replaced it with something that looked like this:
<cfloop ... >
<cfset create() />
<cfloop query="variables.allFloors">
<cfset
createObject('component','com.HotelsOfTheWorld.dao.FloorDAO').init(
variables.Floor[number]).create() />
</cfloop>
The advantage to me was that it fully encapsulated multiple instances of the
subobject - and rather than making it more complicated, it made it a lot
simplier.

Yes, or even not have separate DAOs for the subobjects. If they only
exist inside the composite object and have no relevance to anything
else, there's no real need to create a separate DAO for them (since
you are persisting them as part of the composite DAO already).
KISS / YAGNI would favor having a single DAO for the composite object,
only introducing subobject DAOs through refactoring *if* they needed
to be exposed in the future.
