Re: Service Callback

[SWC <ma...@crissman.net>]

Well, I've since gotten around this issue by changing the service into 
a page, and using an external link to the page with a PageCallback.  
This is fairly inelegant, and I still feel like there should be some 
sort of service callback that I am missing somewhere, but if anyone is 
facing a similar issue, the above solution may work for you as well.
