That depends on the function's attributes. The returnFormat argument will automatically serialize the ColdFusion datatype into a JSON object. I suggest that anyone using it should play with the returns a bit to see what comes back for the different CF datatypes. Most things are fairly standard, with the exception of Adobe's implementation of returning a query. Adobe's implementation provides for a much smaller data return, but it isn't in the standard format used by most other app servers, so it requires a small bit of client-side parsing to get the intended result. Nothing painful, just important to know the difference. I've written a CFQueryReader object for Ext, to parse CF query returns for use with Ext components:
