There are reasons to use CFCs to create output. For example i had an application that required an output of a quite large XML file made up of maybe 50 fragments of XML, out of a possible 300 or so specially formatted fragments. Each occasion the XML was created, the logic CFC would call the appropriate functions in the output cfc, which would produce the relevant fragment of that XML packet, then the logic CFC would stitch them all together into one XML packet and return it to the calling page.
In XML, if you have white space in the wrong place, it can make the whole XML packet invalid, so this was a serious issue for the viability of the whole application. And as i posted in my previous email in this thread, it worked just fine, producing output from the CFC with no extra white space. But you can't just treat it as a normal cfml page inside a cfc. You have to create a variable, containing the bit of html you want to output, then pass that back to the calling page. Otherwise, as you've found, you'll get all kinds of extra white space. As it happened, my XML packets ended up having no spaces AT ALL in them, except for intentional spaces between words in the values of the fields. So i know you can do what you are seeking to do. Another application for CFCs producing output is my CF9 code generator. I have a CFC that examines a database table, then calls a whole series of cfc methods, each of which produces a fragment of code, and the logic CFC stitches them together and writes them out to a file (or files). Kind of like my own form of ORM, that i wrote before i had ever heard of the term ORM. You can do what you want, but as others have said I'd advise putting the logic in one CFC, and the actual output generation in another, just so you organise your code.
