Handle WSDL data connection timeout during PDF generation

     I have created in LiveCycle Designer XDP template. In template i defined WSDL Data connection. For data loading i call xfa.connectionSet.WsDataConnection.execute(0).

     For PDF generation i created LiveCylce process and use generatePDFOutput component.

If WebService works output service generates document with all data - OK.

If i turn off webservice and run process ouputservice generates PDF document with empty fields. Is where any possibility to raise execption to calling process if WSDL connection timeouts or gives SOAP fault error in response? 

I want catch web service errors in process and do not generate PDF if some webservice used in PDF template is not accesible during generation.
