Mayby any of you happend to find solution - i generated classes with  
wsdl4r  
and got this exception, i’m investigating but it’s porbably to deep for  
me and  
solution might be simple (wrong wsdl perhaps)

Little follow up  
from what i’ve found it’s almost certenly bug:

# =============================== item = elements.find { |k, v| k.name == name } if item elename, class\_name = item if klass = Mapping.class\_from\_name(class\_name) # klass must be a SOAPBasetype or a class if klass.ancestors.include?(:🧼:SOAPBasetype) if value.respond\_to?(:data) child = klass.new(value.data).data else child = klass.new(nil).data end else child = any2obj(value, klass) end elsif klass = Mapping.module\_from\_name(class\_name) # simpletype if value.respond\_to?(:data) child = value.data else raise MappingError.new( “cannot map to a module value: #{class\_name}”) end else raise MappingError.new(“unknown class/module: #{class\_name}”) end else # untyped element is treated as anyType. child = any2obj(value) end if as\_array.include?(elename.name) (vars[name] ||= []) \<\< child else vars[name] = child end

elname is never even assigned if item is nil itself

Correct.

If item is nil, the statement immediately below it (elename,  
class\_name = item) will not be executed.

Yea, well quick fix is changing

if as\_array.include?(elename.name)  
to  
if item && elename && as\_array.include?(elename.name)
