Hi  
I have soap server that has WSDL with request containing

\<xsd:element name=“mode” type=“ons:ModeT” /\>

where ModeT is defined as

```
        <xsd:simpleType name="ModeT">
            <xsd:restriction base="xsd:token">
                <xsd:enumeration value="abc"/>
                <xsd:enumeration value="xyz"/>
            </xsd:restriction>
        </xsd:simpleType>

```

I created client using  
SOAP::WSDLDriverFactory.new(\*).create\_rpc\_driver  
and it fails with

/usr/lib/ruby/1.8/soap/mapping/wsdlencodedregistry.rb:151:in  
`base2soap': undefined method`\<=’ for nil:NilClass (NoMethodError)  
from  
/usr/lib/ruby/1.8/soap/mapping/wsdlencodedregistry.rb:127:in  
`simpleobj2soap' from /usr/lib/ruby/1.8/soap/mapping/wsdlencodedregistry.rb:118:in`obj2typesoap’  
from /usr/lib/ruby/1.8/soap/mapping/wsdlencodedregistry.rb:44:in  
`obj2soap' from /usr/lib/ruby/1.8/soap/mapping/mapping.rb:127:in`\_obj2soap’  
from  
/usr/lib/ruby/1.8/soap/mapping/wsdlencodedregistry.rb:210:in  
`elements2soap' from /usr/lib/ruby/1.8/soap/mapping/wsdlencodedregistry.rb:206:in`each’  
from  
/usr/lib/ruby/1.8/soap/mapping/wsdlencodedregistry.rb:206:in  
`elements2soap' from /usr/lib/ruby/1.8/soap/mapping/wsdlencodedregistry.rb:167:in`struct2soap’  
… 18 levels…

changing xsd:token to xsd:string in client fixes problem (but It won’t  
be  
easy to force such change in oryginal WSDL).

Is it just a bug in soap4r, is there anything I could fix on my side?

greetings

ok, right, 1.5.8 works well, thanks
