Migrating RemoteObject components

137

Channels are defined in the 

channels

 section of the services-config.xml file. There are several 

predefined channels that you can assign to your RPC service destinations. For more 
information about channels, see Chapter 43, “Configuring Data Services,” in the Flex 2 
Developer’s Guide.

Logging

The 

<web-service-proxy-debug>

, 

<http-service-proxy-debug>

, and 

<remote-

objects-debug>

 tags in flex-config.xml are no longer used in Flex 2. These were used for 

both client-side and server-side debugging. There is no complete replacement for these. There 
is a new client-side logging API; for more information, see Chapter 11, “Logging,” in Building 
and Deploying Flex 2 Applications. There is also server-side logging that you can set in services-
config.xml to log Remoting Service and Proxy Service traffic; for more information, see 
Chapter 43, “Configuring Data Services,”in the Flex 2 Developer’s Guide.

Migrating RemoteObject components

The server-side configuration for RemoteObject components is now in the 

<remoting-

service>

 section of the services-config.xml file. In Flex 1.5, you configured RemoteObjects 

in the 

<remote-objects>

 section of the flex-config.xml file.

To bind service results in Flex 2, you use the 

lastResult

 property of the service as the 

binding source, as the following example shows:

<mx:Text text="{tempService.getTemp.lastResult}"/>

In Flex 1.5, the 

result

 property was the binding source.

Unnamed RemoteObject

You can no longer use unnamed RemoteObjects. You must configure them in the 

<remoting-service>

 section in the services-config.xml configuration file or a file that it 

includes by reference. Adobe generally defines the Remoting Service in the remoting-
config.xml file, which is included by reference in the services-config.xml file.

In Flex 1.5, you could specify 

source="object_name"

 and the object’s statefulness on the 

RemoteObject tag. In Flex 2, you configure the object name and its statefulness in the 
configuration file.
