Hi,

I am getting this error in client side when I expect an array in  
response . Response with single element works fine

C:/Ruby/lib/ruby/1.8/soap/mapping/encodedregistry.rb:530:in  
`soap2typedobj’: unknown class: (SOAP::Mapping::MappingError)

InputList  
class InputList \< ::Array  
end

class SubData  
attr\_accessor :Id  
attr\_accessor :val1  
attr\_accessor :val2  
attr\_accessor :Name

def initialize(Id = nil, val1 = nil, val2 = nil, Name = nil)  
@Id = gISId  
…  
end  
end

=DataOutput  
class DataOutput \< ::Array  
end

Array is of type SubData defined above

Please help to solve this error ?

Regards,  
Prashant

When I use my class DataOutput I get following error
