From: raja@... Date: 2006-07-20T06:28:55+09:00 Subject: passing nil to WSDL function Consider the following script: I want to pass nil to 'eventId' instead of 0. But ruby spits out error if i try to use nil. It works for 0. soap = SOAP::WSDLDriverFactory.new(wsdl_url).create_rpc_driver soap.wiredump_file_base = "soapresult" parameterMap = { "versionSetName" => "live", "eventId" => 0, } print "\nCAlling getVersionSet...\n" result = soap.getVersionSetFile(parameterMap) Thank you, Raja
