Problem with returning empty array

Hi, I'm getting an error from VB.NET when consuming a PEAR::SOAP webservice that sometimes returns an empty array. Everything works fine when the array is populated, however when the array is empty I get an xml error, the wire is: <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns4="urn:EncoderIntegrator" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"> <SOAP-ENV:Body> <ns4:getControlMessagesResponse> <messages xsi:type="SOAP-ENC:Array" SOAP-ENC:arrayType="[0]"/> </ns4:getControlMessagesResponse> </SOAP-ENV:Body> </SOAP-ENV:Envelope> Now, I'm no expert but I don't believe that '[0]' is valid for an arrayType, is this correct? Any ideas on why that's getting in there? My return function is doing the following ($messages is an empty array): return new SOAP_Value('messages','{http://granicus.com/xsd}ControlMessageList',$message s); ControlMessageList is defined as: $this->__typedef['{http://granicus.com/xsd}ControlMessageList'] = array(array('{http://granicus.com/xsd}ControlMessage')); ControlMessage is defined as: $this->__typedef['{http://granicus.com/xsd}ControlMessage'] = array( 'Message' => 'string', 'AssetID' => 'int', 'Seconds' => 'int' ); Oh, and I'm using 0.7.5 Thanks! -Javier
