RE: Header and Detail

It depends on the access.  If you access by ordinal position, then leaving 
something a Vector is "okay", except that you always have to cast it.  I 
usually start with Vectors for those kind of collections, and then eventually 
replace the Vectors with my own class (I keep waiting for Java to support typed 
Vectors as an integral part of the language).

So, iscmControlList is probably okay to leave as a Vector for now.  However, 
what iscmControlList returns (let's call it FieldRow) is a collection of 
FieldDefinitions that you have to access by key.  This is definitely NOT a 
Vector.  In fact, you may want to consider subclassing Hashtable instead of 
Vector, because Hashtables provide keyed access.  In any case, the code that 
you have in FieldFormatter that pulls an individual FieldDefinition out of a 
FieldRow definitely has no business in FieldFormatter, it should instead be a 
method in FieldRow.

Using this (which makes sense) my getRecord method for icsmControlList will
have to return something other than a vector object, right?  I'd have to
make my own class (FieldRow or something) that it would return.  Then write
my own getField method for the FieldRow class.

But in this case, FieldRow is nothing more than a vector (or fields).  So is
there an advatange to this, or is this just not right to begin with?

(My comparable code)
sendID =
FieldListFormatter.getField((Vector)icsmControlList.get(i),"SND_ID").data;
