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

Can I see the WSDL and the error message you get? How it’s going when  
you remove ‘eventId =\> 0’ ?
