For ColdFusion, I prefer presentation elements (we are talking about
HTML/XHTML/XML for the most part, right?) to be in tags.
The main reasons are simple.
I'd rather see:
<ui:navdiv>
<a href="home">home</a>
</ui:navdiv>
Than
<cfsavecontent variable="myvar">
<a href="home">home</a>
</cfsavecontent>
<cfset WriteOutput(obj.showNavDiv(myvar))>
Or variations along those lines. The tag based solution feels like a natural
fit alongside the tag based output for the most part, and it seem like a
cleaner method to wrap with tags than if you are using CFCs, and finally, it
appears that you will have no choice on using tags for UI, then it makes
sense to me to always use tags for UI, for consistency sake.

Subject: RE: (OO) UI in CFCs
Personally, I don't see a reason not to have a separate CFC just for UI
elements that go on a page. Basically, you have a page which calls a BL
(business logic) CFC for logic and a UI (user interface) CFC for specific UI
elements that go on the page with the business logic.
Take an average blog for example. Most have a calendar on the side. Why is
this not inside a blogui.cfc file with other specific UI elements that are
re-used. Yes, a custom tag can be built for each of the UI elements but on
an average blog, there are 4 or 5 different small side elements. A single
location for all of them would make sense rather than 4 or 5 different
modules.
At the moment I'm not using CFCs for UI but for UI elements less than 10
lines long, it's looking good.
