Nillable namespace not getting added automatically
I have defined an element as Nillable in my XSD but when I am importing the WSDL in SOAP UI, the nillable namespace is not getting generated and I get the "Attribute not allowed (no wildcards allowed) : xsi:nil in element" error.
I even tried by manually adding the namespace in the xsd (and I can see that it is present in the WSDL) but when imported in SOAPUI it doesn't reflect.
The only solution that works is that I manually add the namespace in SOAPUI request but I cannot ask my consumers to do the same. Kindly suggest.
