Taxonomy.selectNodes work only when testing services from admin

Hello,

I have a strange behaviour... I enabled the services modules, amf module, put amfphp 1.9 beta2 in the correct directory. When I test, all seems ok. I enable the taxonomy services (and system and node services).
When I test the taxonomy.selectNodes in the admin service pages, all is ok, service return to me some data (from two differents kind of content).

When I create a flash application (not flex, only flash) and try to get data with the nl.dpdk.services.gephyr framework, amfphp never finish the call of the same method...

I tried with some params, but no idea to find solution...

		private function _connectToDrupal():void
		{
			trace( "try to connect to drupal... 1" );
			_service = new DrupalService( this._gateway );

			_service.addEventListener(DrupalEvent.SYSTEM_CONNECT, 				this._onSystemConnect);
			_service.addEventListener(DrupalEvent.ERROR_SYSTEM_CONNECT, 		this._onSystemConnectError);

			_service.addEventListener(DrupalEvent.TAXONOMY_SELECTNODES, 		this._onSelectNodes);
			_service.addEventListener(DrupalEvent.ERROR_TAXONOMY_SELECTNODES,	this._onSelectNodesError);

   			_service.systemConnect();
			trace( "try to connect to drupal... 2" );
		}
		 
		private function _onSystemConnectError( event:DrupalEvent ):void
		{
			trace("on system connect error : " + event.getError() );
		}
		 
		private function _onSystemConnect( event:DrupalEvent ):void
		{
			trace( "try to connect to drupal... 3" );
			_service.taxonomySelectNodes( [1] );
		}
		
		private function _onSelectNodesError( event:DrupalEvent ):void
		{
			trace( "on select nodes error : " + event.getError() );
		}
		
		private function _onSelectNodes( event:DrupalEvent ):void
		{
			trace( "on Select Nodes !!" );
			var o:Object = event.getData();
		}
		

The systemConnect method is ok, a node.get is already ok, but the taxonomy.selectNodes don't return anything... If I put no tids (an empty array) amf send to me a return, but since I add a tid in the array nothing append after the call.

The two calls in Charles :

code without any tid :

<?php
// call
AMF Message	Message	
	Header		
	Body		
		[0]	Body Part	
			Target	String	taxonomy.selectNodes
			Response	String	/1
			Content	Array	
				[0]	Array	
				[1]	Array	
				[2]	String
				[3]	String

//response :

AMF Message	Message	
	Header		
		[0]	Header Part	
			Name	String	AppendToGatewayUrl
			Must Understand	Boolean	false
			Content	String	?SESS18dbcf0d321fb279bd51ea45b7d24b2b=87ikcam4psa7mibgsph62v6if4
	Body		
		[0]	Body Part	
			Target	String	/1/onResult
			Response	String	null
			Content	Null	
?>

code with tid :

<?php
// call
AMF Message	Message	
	Header		
	Body		
		[0]	Body Part	
			Target	String	taxonomy.selectNodes
			Response	String	/1
			Content	Array	
				[0]	Array	
					[0]	Integer	1
				[1]	Array	
				[2]	String	
				[3]	String	

// response 
taxonomy.selectNodes	Method	AMF data is incomplete (0 bytes of 0 bytes). Please check the recording limits in the Recording Settings.
	Parameters	Array	
		[0]	Array	
			[0]	Integer	1
		[1]	Array	
		[2]	String	
		[3]	String	
	Result	Null	
?>

It's obvious for me, and I don't know if it's the DrupalService framework in cause or the amfphp service... If anyone can help me I'm listening for any suggestion.

Thanks in advance.
