Re: CFCs CFMX 6.1

[Matthew Woodward]

Not sure if that was part of the page context bug or not--I didn't 
experience that one.  I used CFCs in both Application and Session scope with 
no problem, so it sounds like what I'm describing was a separate issue.  To 
give a specific example, say I have a Cart object that I instantiate (let's 
be original and call it "myCart") for a particular user and put it in 
Session scope.  Within myCart let's say there's a database call of some 
sort, and since I use MVCF, the datasource is called as 
#Application.stConfig.DSN#.  myObject will choke on this and give an error 
along the lines of "APPLICATION is undefined."

If you copy the Application scope structure and pass it into the CFC, you're 
fine, but what I did was decided to make the objects in a couple of my 
projects a little more "dumb" than they otherwise would be, and have static 
helper classes handle all the database interaction.  Worked well, and even 
with this as well as the super limitation, CFCs were still a godsend on a 
couple of large projects that would have been far nastier in CF5.

Now I'm tempted to drop what I'm doing and test this out--I'll keep my 
fingers crossed that this is fixed.

I'd forgotten hearing about that... wasn't that part of the same page 
context(?) bug where the server stamped the cfc with the request it was 
created on so if you stashed the cfc in the application scope you didn't get 
display from it after the fact? ... Or were those separate issues? ... I 
knew there were good reasons I'd stayed away from doing much with MX until 
now. :)
