That's a really clever idea. I'm a FB guy so I never really been in that
situation (and I usually prefer to generate all error message not just the
first), but if that's what you're looking for, I'd say it's a perfect
solution.
Here's a different take on the same idea, except using the same template as
both the form and the validation custom tag. Obviously have to flesh it
out, but it'll let you have both your custom tag and your consolidated code
all in one.
------------------------------------------------------------------------
<cfif isDefined("thistag")>
<!--- validation --->
<cfif len(form.email) EQ 0>
<cfexit method="exittag" />
<cfelseif ... >
...
</cfif>
<cfelse>
<!--- form --->
<cfif isDefined("form.myFirstField")>
<cfmodule template="#getFileFromPath(getCurrentTemplatePath())#" />
</cfif>
<form ...>
...
</form>
</cfif>
