Re: Null values and WSDL2RPG and HTTPAPI?
Mike,
Thanks for that link, very useful.
interesting that the document says "There are two ways to represent a
null value with elements: with either the attribute nillable="true",
or with minOccurs="0""...
So in the WSDL I have, the element definitions are somewhat
contradictory as minOccurs="1" meaning NOT NULL yet nillable="true".
I suppose it makes sense if we think of it as, "every element is
required" but some may be nillible...

According to this http://www.ibm.com/developerworks/xml/library/ws-tip-null.html you might get a null value indicator in the attribute but the value of the element will still be zero length.
