Wow, well, I wouldnt normally recommend outputting directly like that
- but if it solves your problem, more the better. Boy am I glad
returnFormat was added to CF8.

Here's a good blog entry which gets to the heart of your problem:
http://www.talkingtree.com/blog/index.cfm/2005/6/15/DevNet2Developer
There are a few comments that are bit "looney", but I think you can find
enough information on that page to resolve your issues.

So that would get rid of the "WDDX-ifying" -- but I'm still left with
fighting that META tag CF puts in there.
I work from a network, and there are definitely other people using the CF
server, so I'm not sure how I'll be able to get around the single IP issue,
but I can definitely look into the Spry code and try to find a place to
strip out the META tag. Let's see if I can make this work!
Thanks Andrew, Ray, and Dan!

Ray,
I use CFC's all the time with Json, the trick is not to use the cfreturn tag
under cfmx7 and below but to output it instead.
Have a look at how I do it with http://CFJsonService.riaforge.org and you
see what I mean.

So two people say its the META tag, and I'm sure that's right, but no
one else also thinks he has an issue with the WDDX-ifying as well?

Yes, the Dev Net tag breaks things. The easiest solution is to just stop
using the Dev Net edition and go to the Developer Edition.
The Dev Net Edition has unlimited IPs, but places the meta tag in each
request automatically.
The Developer Edition is limited to a single visiting IP address.
They both are essentially the same as the Enterprise version with their own
restrictions.

Yes the issue is the meta tag.
Having done a lot of Dojo work and also creating
http://CFJsonService.riaforge.org I found that you can't evaluate a json
object if there is something there that is not json expected.
Your only bet is to modify the call, where it does the http request within
spry, and do something like this.
var strTest = http.responseText;
strTest = strTest.replace(/(<\/?META[^>]*>)/gi,'');
Which removes the meta tag.

I've got a webservice running that converts some various CF objects into
JSON - Seems to be working alright, but I'm running into a vexing issue.
When I call the service via Spry, I get an error from SpryDebug.js:
"Caught exception in JSONDataSet.loadDataIntoDataSet: SyntaxError: missing }
in XML expression"
What's confusing is that if I call the service myself, copy the contents
into a .js file, and then have Spry call straight from that .js file, it
works just fine! Here's the JSON my Service returns, if that helps:
{
"recordcount":3,
"columnlist":"categoryid,matchid,name",
"data":
{
"categoryid":[3,3,3],
"matchid":[1,2,3],
"name":["some dude","random guy","joe schmoe"]
}
}
My service code (condensed) is pretty basic. I pass in a Query object
(results) and tell CFJSON to format it as a query:
<!--- transform the result into JSON --->
<cfset results = Variables.jsonCFC.encode(
data = results,
queryFormat = "query"
)
/>
<cfreturn results />
I am running on a development server, so I get that meta data on every CF
request:
<META NAME="ColdFusionMXEdition" CONTENT="ColdFusion DevNet Edition - Not
for Production Use.">
Could that be the culprit? If so, how do you guys develop AJAX apps without
running into this issue?

Could be two things here. First - yes - that meta tag could most
likely be breaking stuff. I don't know as I run a non-dev edition
locally.
Secondly - and this is what concerns me the most - do not forget CFCs
return data in XML. Either WDDX form or plain XML.
So even though you returned JSON, it was turned into XML. Not
translated, wrapped I should say. You would need to point Spry to a
CFM page instead.
FYI, CF8 fixes this by letting you specify a return format for CFC methods.
