Flash CS 4 - amfphp 1.9 beta2 - Error #2173

[Novick]

Hi!
Please help in my problem! Thanks!
I create class Array in IDE Flash CS 4, and send it cross class NetConnection to amfphp 1.9:

Code:

var gateway:String="http://localhost/amfphp/gateway.php";
var myresp:Responder=new Responder(myresp_onResult,myresp_onFault);
var connection:NetConnection=new NetConnection;
connection.connect(gateway);
var myar:Array=new Array(1, 2, 3);
connection.call("myservice.getData", myresp, myar);
function myresp_onResult(result:Object):void {
}
function myresp_onFault(fault:Object):void {
}

I take trace of this run-time error:
ArgumentError: Error #2173: It is not succeeded to read an object in a stream. In a class flex.messaging.io.ArrayCollection
an interface is not realized flash.utils.Iexternalizable,
but as his pseudonym a class is used with support of external connections.

I use often amfphp but never receives this error. I guess parenthesis are optional, but try with:

var connection:NetConnection=new NetConnection();

Did not help
That characteristically, an error appears only at transmissions of Array. For class ByteArray, String, Number, Boolean - all be well.

did you use charles, or any other trafic debuging tool?

[Novick]

No, only IDE Flash CS 4 (AS 3.0, ObjectEncoding.AMF3) - amfphp 1.9 beta2 on localhost (Win XP SP3, WampServer 2.0 - my educational system)
Now I decide a problem so:
I will transform an Array in a String and send to the server.
With difficultly component Arrays did not work while.

[Ronald Wernecke]

I beleive, the problem is somewhere in the data stream.
After it is allways good to know how the traffic moves

Look into the traffic - use charles for debuging

[Novick]

News from error:
It takes place, when amfphp return type Object.
Exemple:

Code:

<?php
function getData($flashArray){
  return mysql_query("SELECT * FROM myTable");
}
?>

Can anybody to me help from specialists?

Mysql recordset are one of the oldest elements amfphp deal with ... check trough another server, or try resintalling to the last version of amphp

did you run this with phpMyAdmin?
did you check charles for details?

No! I search answer, but no new question!

[Ronald Wernecke]

it is allways wise to run sql commands, not delivering the expected results, against phpMyAdmin, to make sure they are not the reason.

And further - if you dont receive the expected result from a remote client, it makes sense checking the communication.

copy the query command into the SQL-Window in your phpMyAdmin, so you know that this is running, and execute the programm while charles is running, to make sure the data communication is as expected.

If you receive errors, or things look different, you get away from guesswork towards well based debugging.

... only IDE Flash CS 4 (AS 3.0, ObjectEncoding.AMF3) ...

Sending arrays back from the 1.9 AMFPHP beta has a few documented issues, most notably that it doesn't work reliably with AMF3 Objectencoding.
Using AMF0 should fix your problem.

However AMF3 is neccessary for many other transfers, such as handling ByteArrays. You can set different encodings for different calls of course, not sure if that would have a downside though.

Thanks!
It's true - in AMF0 this truble I not meeting.
