David Garcia commented on AXIS2-1883:
-------------------------------------
Hi again,
Finally, we´ve decided to fix bug on the assumption that null values are
allowed to pass through SimpleTypeMapper.
To solve all our issues with null values we also had to fix AXIS2-1745; that´s
why we´ve attached a patch for BeanUtil.
Both patches have been generated against the latest sources in the "1_1" branch.
We have thoroughly tested this solution with our use cases and it works fine so
far :-)
I hope it also works for others.
BTW, I´ll post another comment on AXIS2-1745 to link here.
Cheers,
David

> A property of a complex type is defined like this:
> <xs:complexType name="SomeBean">
> <xs:sequence>
> <xs:element name="someInt" nillable="true" type="xs:int"/>
> ...
> </xs:sequence>
> </xs:complexType>
> That complex type is used as the input parameter of a service´s operation and
> is defined like this:
> public class SomeBean {
> private Integer someInt;
> ...
>
> ...getters & setters...
> }
> Then, trying to set that property to "nil" is not allowed.
> That is, if the input message is something like this:
> <soapenv:Body>
> ...
> <someInt xmlns:nil="http://www.w3.org/2001/XMLSchema-instance";
> nil:nil="true"/>
