[otrs] Error parsing Invoker-respons

Sorry for the remail, this time with all info. For my OTRS-setup I have an Invoker which logs every closing of tickets. In the response I have the log entry-id which I save in a Dynamic Field. This is done correctly. Unfortunately, in the otrs.log file, I keep seeing the following messages: [Mon Sep 17 11:00:22 2012][Error][Kernel::System::Main::_Dump][841] Unknown ref 'Struct'! [Mon Sep 17 11:00:23 2012][Notice][Kernel::Scheduler::TaskHandler::GenericInterface::Run] GenericInterface task executed correctly! When I set the webservice debugging to Debug I can see the following item 'Struct': Incoming data before mapping (2012-09-17 11:00:22.000, debug) $VAR1 = { 'return' => bless( { 'ArticleID' => '17120', 'Respons' => 'OK', 'ResponsMessage' => '9836' }, 'Struct' ) }; When I check the received XML it shows as follows: http://schemas.xmlsoap.org/soap/encoding/" xmlns:soap-enc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/"> soap-env:body xmlns:Logresponse <return xsi:type="SOAP-ENC:Struct"> <articleid xsi:type="xsd:string">17120</articleid> <respons xsi:type="xsd:string">OK</respons> <responsmessage xsi:type="xsd:string">9836</responsmessage> </return> I personally think that the "Struct" in the Bless() (in the data before mapping) is causing this error, but I am unaware how to fix this issue. Where can/should I start? Is this a bug, that the XML cannot be parsed correctly? My setup is: Windows Server 2008 R2 - MS SQL 2008 R2 - OTRS 3.1.10 Thanks for any reply! Regards, Dionysius
