I have an application developed in Flex 2 that loads another
application built in Flash 8. Since they need to send some small
data back and forth, I am using two LocalConnections - one for
sending data from the Flex app to the Flash 8 app, and one for the
reverse. Each uses a hard-coded name for simplicity's sake. All the
data sent are intrinsics (Strings and Numbers)
So far, so good. Both sides send and receive the communications and
the correct method calls are executed, but I've noticed some quirks
with the arguments received by the functions on either side. On the
Flex side, the client functions that take no parameters receive an
argument array that looks like Array[Array[]] (an array of a single
item which is an empty array), which throws a runtime error. On the
Flash side, I've noted problems with the String objects where Flash
cannot properly execute String methods on them. Also, in a function
taking two String parameters (param1:String, param2:String), it is
receiving param1='param1,param2' and param2=undefined from the
LocalConnection. I've included sample code (including my
workarounds) for all these cases below.
I've been unable to find any documentation or discussion mentioning
any of these issues. Although they have fairly simple workarounds,
it seems odd to find no mention of anything like this. Does anyone
know if these are known issues, or am I missing something?
Thank you,
Heidi Hunter
// Sample Flex code
class LocalConnectionReceiver{
// only one of these exists at any time
private var connection:LocalConnection;
function LocalConnectionReceiver(){
connection = new LocalConnection();
connection.client = this;
connection.connect("flexLCListener");
}
// workaround for empty args array, I previously had
// function onFlashResize():void{
function onFlashResize(...arguments):void{
// do something
}
}
class LocalConnectionSender{
// used by any Flex component needing to communicate with the
Flash app
private var connection:LocalConnection;
public function send(method:String, ...arguments):void{
connection.send("flash8LCListener",method,arguments);
}
}
// Flash8/AS 2 code
class FlexConnector extends LocalConnection{
function FlexConnector(){
super();
connect("flash8LCListener");
}
// I want to do :
// function setInfo(param1:String, param2:String):Void {
// but my workaround is:
function setInfo( params:String ):Void{
// I want to do:
// var split:Array = params.split(",");
// but I get split = undefined
// workaround:
var paramString:String = String(params);
var split:Array = paramString.split(",");
var param1:String = split[0];
var param2:String = split[1];
// do something with param1 & param2
}
function sendToFlex(method:String):Void{
var sendConnection:LocalConnection = new LocalConnection();
sendConnection.send("flexListener",method,arguments.slice(1));
}
}
