SQLStatement.parameters not working inside .text properly? What am I doing wrong

Question

I'm having trouble with parameters in the SQLStatement class.
Look at this code:
var stmt:SQLStatement = new SQLStatement;
stmt.text = "INSERT INTO user VALUES(@title, @firstname,
@lastname)";
stmt.parameters["@title"] = "Mr";
stmt.parameters["@firstname"] = "Simon";
stmt.parameters["@lastname"] = "Whatley";
trace(stmt.text);
trace(stmt.parameters["@title"]);
Now, you would expect this to trace the stmt.text as
"...Simon, Whatley)"
However, this is my trace:
INSERT INTO user VALUES(@title, @firstname, @lastname)
Mr
So, this means the parameters are working great on their own,
but just not inside the .text property?
Or is this the way it's suppose to show, and to be converted
later on in the execute method?
I've tried both with "@" and ":" as parameter
declaration.

My apologies for not finding this out until after my first
post,
Apparantly it is working fine, just not if you trace the
.text property itself.
When inserting into a database it gets the proper values.
To not make this thread utterly useless; does anyone know any
possible way to trace the .text property with the parameters
properly assigned? Without going "all the way"?
