What you could also do is define your own collection type - an
ArrayOfComments.cfc that only allows instances of Comment.cfc. Then you
return that from BlogPost.getComments(), and implement your various
addComment(), removeComment() functions there.

Another option is to roll your own date object and pass an instance of
it into the function instead.
Actually, this could be one way around the whole type safety / null
problem with cf - develop a system of object types (Date.cfc,
Integer.cfc, String.cfc, etc). Then you could choose to work with
Kerry,
You would define you're own rule for what a NULL is for that type
since you're creating the component.
If a zero-length string is a null to you thens ure isNull would return
true. if the rule was the string had to be equal to NULL then no, a
zero length string would return false.

only if it had never been set:
cfset myString = createobject(component,types.String)
cfoutput#myString.isNull()#/cfoutput --- should return true ---
cfset myString.init(Hello World)
cfoutput#myString.isNull()#/cfoutput --- should return false ---

i'd go with objects are null until explicitly initialized - you could
track it with a private attribute and then toggle that from within the
init method. You don't ever need to nullify an object once it has been
initialized...

or, if you did want to null the object you could have a method,
setNull() which just turns the flag back on.
cfset myString = createobject(component,types.String)
cfoutput#myString.isNull()#/cfoutput --- should return true ---
cfset myString.init(Hello World)
but then you'd be open to the weird situation of having an object that
claims it is null but contains a value.
If you need a null object, just create a new one and don't initialize
it.

i think my setNull function would probably clear out the value.
not calling the init function on create seems a little sketchy to
me. It is common practice in almost all CFC discussion on this list
to call init during creation as the constructor method.
I would prefer to explictly set the
just a nasty little idea for re-nulling an object:
function setNull(){
this = createobject(component,getMetaData(this).name);
}

Maybe you could have two different objects: a value object and a null
object. For example, you could have a Date object that always has a
value, and a NullDate that extends Date and doesn't have a value.
- You don't skip the init method. (Bill's concern.)
- An object can't simultaneously have a
the problem is that you need a solution that works for all data types,
not just dates - so you wind up with a NullDate.cfc, NullString.cfc,
etc. If you want nullifyable objects, then Kerry's proposed setNull()
method looks like the way to go (IMHO)

Just found the list of BOFs for MAX was released, and there is no CFC
BOF this year. :( Two years ago I ran an unofficial BOF. If there is
enough interest in an unofficial CFC BOF this year, let me know and
I'll see what I can work up.

I enjoyed last years, was that official or un-official. I would definitely
attend one this year official or not.

Two years ago it was unofficial. So I ended up renting a room from the
hotel for the meeting. Someone paid for it, I forget who. Last year it
was official.

If I could make it, I would be there.
After the hotel bill at CFUNITED, my company limited me to one

Hi guys,
Just stumbled across a code generation tool which looks pretty impressive. I didn't write it (so have no vested interest in it) but it does look promising. It can connect to lots of different databases and allows you to write your code gneration templates in JScript, _vbscript_, C# or

Ray, I'd be up for a CFC BOF, assuming there aren't 20 other things
competing for my attention during that hour. ;)

Thankfully they took care of the two pre classes, the plane, the car ,
the hotel and all of the Pepsi's I drank (wink) for 5 days.
HOTEL= $1200
Car = $500
Plane = $600
CFUNITED = Priceless
Oh wait, They forgot to mention the rest of the four thousand dollar
AMEX bill !!

I think this is very important, Ray. If you need any help, I'd be happy to
lend a hand.

I'm looking for a DAO generator for CF at the moment.
the trouble is, I know exactly what I want but can't find the right
one. Can anyone suggest a DAO generator?
