I've got to make this quick because I need to run out to my other client
(the one where I'm having this problem). But I just tried a very similar
thing where I'm at right now. I've attached the CFC, and I'm calling it like
this:
<cfsetting showdebugoutput="no">
<cfset EmailBody = Trim(form.Body)>
<cfset Email = CreateObject("component", "CFC.Email").init(Subject="Pay No
Bill Report", Sender="[EMAIL PROTECTED]",
Recipient="#form.RecipientList#", Body="#EmailBody#")>
<cfset Email.sendEmail()>
And this one works perfectly! I just don't know what I'm doing wrong with my
LienApplication CFC. :o/
