Using the Flash Remoting service with ColdFusion pages
When you build a ColdFusion page that interacts with a SWF application, the directory name that contains the
ColdFusion pages translates to the service name that you call in ActionScript. The individual ColdFusion page names
within that directory translate to service functions that you call in ActionScript.
Note: Flash Remoting cannot interact with virtual directories accessed through a ColdFusion mapping.
In your ColdFusion pages, you use the Flash variable scope to access parameters passed to and from a SWF application.
To access parameters passed from a SWF application, you use the parameter name appended to the
the array. To return values to the SWF application, use the
Flash.Params
increment value for records in a query object to be returned to the SWF application, use the
The following table shows the variables contained in the Flash scope:
Variable Description
Flash.Params Array that contains the parameters passed from the SWF application.
If you do not pass any parameters,
empty.
Flash.Result The variable returned from the ColdFusion page to the SWF
application that called the function.
Because ActionScript performs automatic type conversion, do

Flash.Pagesize The number of records returned in each increment of a record set to a

ActionScript 1.0 and ColdFusion use case insensitive data structures to store associative
arrays, objects and structs. The Java representation of these data types requires a case-
insensitive Map, which the gateway achieves by forcing all keys to lowercase.
ActionScript 2.0 is case sensitive and requires a <lowercase-keys> tag value of
