Hi Alex,

Parameters is null upon entry into AbstractOperation.sendBody?
Yes it is null.
I would think you would get a different exception. I don’t have a
test case to debug, but the code looks like if you call
Operation.send() with no args, then sendBody would get an empty array
and you would get the exception you posted.
Exactly.
If parameters is null on entry, then it is probably worth figuring out
why it is null and not an empty array.
The issue not the "parameters" to be null Alex, flex works with this way.
The signature of method :
override public function send(... args:Array):AsyncToken
and in this method :
override public function send(... args:Array):AsyncToken
{
if (_multiService != null)
_multiService.initialize();
if (operationManager != null)
return operationManager(args);
var params:Object;
var filter:SerializationFilter = getSerializationFilter();
if (filter != null)
{
===> params = filter.serializeParameters(this, args);
}
The marked line creates array for params in both Royale and Flex.
Things changes from here the
sendBody(parameters:Object):AsyncToken
of AbstractOperations of Flex, can handle the new array but Royale can not.
In flex,
if (ctype == CONTENT_TYPE_XML)
{
if (parameters is String && xmlEncode == null)
{
paramsToSend = parameters as String;
}
else if (!(parameters is XMLNode) && !(parameters is XML))
{
if (xmlEncode != null)
{
var funcEncoded:Object = xmlEncode(parameters);
if (null == funcEncoded)
{
token = new AsyncToken(null);
msg = resourceManager.getString(
"rpc", "xmlEncodeReturnNull");
fault = new Fault(ERROR_ENCODING, msg);
faultEvent = FaultEvent.createEvent(fault, token);
new AsyncDispatcher(dispatchRpcEvent,
[faultEvent], 10);
return token;
}
else if (!(funcEncoded is XMLNode))
{
token = new AsyncToken(null);
msg = resourceManager.getString(
"rpc", "xmlEncodeReturnNoXMLNode");
fault = new Fault(ERROR_ENCODING, msg);
faultEvent = FaultEvent.createEvent(fault, token);
new AsyncDispatcher(dispatchRpcEvent,
[faultEvent], 10);
return token;
}
else
{
paramsToSend = XMLNode(funcEncoded).toString();
}
}
else
{
var encoder:SimpleXMLEncoder = new
SimpleXMLEncoder(null);
var xmlDoc:XMLDocument = new XMLDocument();
//right now there is a wasted <encoded> wrapper tag
//call.appendChild(encoder.encodeValue(parameters));
var childNodes:Array =
encoder.encodeValue(parameters, new QName(null, "encoded"), new
XMLNode(1, "top")).childNodes.concat();
for (var i:int = 0; i < childNodes.length; ++i)
xmlDoc.appendChild(childNodes[i]);
========> paramsToSend = xmlDoc.toString();
}
paramsToSend = xmlDoc.toString(); is return value.
In royale ;
if (ctype == CONTENT_TYPE_XML)
{
if (parameters is String && xmlEncode == null)
{
paramsToSend = parameters as String;
} else {
===> paramsToSend = parameters.toXMLString();
}
paramsToSend = parameters.toXMLString(); is called which throws
exception.
checking parameters for if an empty array and than returning
paramsToSend = parameters as String;
may remove exception.
Thanks,
Serkan

Actually "parameters" is null but converted to something in
AbstractOperations.
Checking the object if array and size is my first choice, I wanted to
discuss if we need different approach .
Than if we agree I can create PR.
Thanks,

It is unlikely that XMLNode is a factor. More people used e4x
than flash.xml.
I’m confused because the screenshots indicate that parameters is
not null or an array but rather, some string that begins with “user
Assuming there is no “request” or “argumentNames” property, then
it looks like Operation will pass sendBody an empty array as
params so maybe check for params is Array and params.length = 0;

The problem is not about "parameters" to be null but the handling
of the null valued parameter by Royale.
25.06.2020 20:26 tarihinde serkan yazdı:
If we consider authAndCall of BasicAuthenticationHandler at
line 69, send() is called.
if (parameter == null) {
*return /* implicit cast */
org.apache.royale.utils.Language.as(service.operations[operationName].send(),
mx.rpc.AsyncToken, true);*
}
return /* implicit cast */
org.apache.royale.utils.Language.as(service.operations[operationName].send(parameter),
mx.rpc.AsyncToken, true);
For here, the function being called is
"mx.rpc.http.Operation.prototype.send()"
The suspendapp method of menubar :
private function
suspendApp(eventObj:CloseEvent):void {
if(eventObj.detail == Alert.OK) {
suspendAppResult.token =
BasicAuthenticationHandler.authAndCall(jobManagerService,
"suspendapp");
}
}
I can share the sources for
com.likya.pinara.utils.BasicAuthenticationHandler and
com.likya.pinara.comps.MenuBar if you prefer.
Thanks,

I have no idea where “parameters” came from and what it
is. Which method in the call stack created what is
“parameters”? Maybe suspendApp? Or authAndCall?
I think we need to understand why Flex has null at some
point but Royale doesn’t.

*Subject: *empty object is being behaved as if an xml
Hi,
Regarding the exception :
When the "parameters" is null it is being behaved like an
xml node by AbstractOperation with the code piece below :
if (ctype == CONTENT_TYPE_XML)
{
if (parameters is String && xmlEncode == null)
{
paramsToSend = parameters as String;
} else {
paramsToSend = parameters.toXMLString();
}
In fact Flex version checks if it is XMLNode or not than
creates some kind of empty XML "<>"
How can I check if "parameters" is not an xml string and
convert it to empty xml string ? Checking null is not
working because it is not null in royale bu an empty
Array, which is an object according to the code below :
Thanks,
Serkan
