Using the Flex Data Service Assembler

Example application

This section describes creating a Flex application that uses the ColdFusion Data Service 
adapter and Flex Data Service assembler so that a ColdFusion component handles the back-
end database management.

You can download the source code for the files that are included in the Flex sample Contact 
application from “

.” In addition, you can view the code for the Flex sample Contact 

To use ColdFusion instead of the Java adapter:

1.

Create the assembler CFC. 

2.

Create the DAO CFC.

3.

Create the Value Object CFC.

4.

Specify the destination in the data-management-config.xml file.

5.

Copy the files for the Flex Contact sample application to the appropriate folders.

6.

Run the application.

Creating the assembler CFC

The assembler CFC contains the 

fill

, 

sync

, 

get

, and 

count

 methods.

Creating the fill method

In the Contact sample application, the fill operation has two forms: one that takes no 
argument, and one that takes a string. The corresponding Java function returns a List of 
Contact objects. Because a List corresponds to an array in ColdFusion, the 

fill

 method 

returns an array of Contact objects. The 

fill

 method appears as follows:

<cffunction name="fill" output="no" returntype="samples.contact.Contact[]"

access="remote">
<cfargument name="param" type="string" required="no">

<cfset var ret = ArrayNew(1)>

<cftry>

<cfset dao = CreateObject("component","samples.contact.ContactDAO")>

NO

To make creating the CFCs easier, ColdFusion MX 7.0.2 includes wizards that you 
can use in Flex Builder. For more information, see
