Optional elements of complex type must be present just empty

[Monica Ferrero <mf...@accelrys.com>]

Hi!

I have wsdl first service, snippet below, with a  type getxxx (request
parameters for the corresponding getxxx method) which contains two optional
string arrays. If the optional string arrays are not present CXF fails. If
they are present but empty, things work fine.
Why is this? How can I allow for the array elements not to be present at
all in the SOAP message?
I'm using CXF 2.0.4.

So

<getxxx xmlns="http://myservice.bbb.aaa.com/
"><id>1</id><var1>0</var1><var2>5</var2></getxxx>

fails, but

<getxxx xmlns="http://myservice.bbb.aaa.com/
"><id>1</id><array1/><array2/><var1>0</var1><var2>5</var2></getxxx>

is ok.

Thanks for you help,

Monica

wsdl:
            <xsd:complexType name="StringArray">
                <xsd:sequence>
                    <xsd:element name="item" type="xsd:string" minOccurs=
"0" maxOccurs="unbounded"/>
                </xsd:sequence>
            </xsd:complexType>

            <xs:element name="getxxx" type="ps:getxxx"/>
            <xs:complexType name="getxxx">
                <xs:sequence>
                    <xs:element name="id" type="xs:int"/>
                    <xs:element maxOccurs="1" minOccurs="0" name="array1"
type="ps:StringArray"/>
                    <xs:element maxOccurs="1" minOccurs="0" name="array2"
type="ps:StringArray"/>
                    <xs:element name="var1" type="xs:int"/>
                    <xs:element name="var2" type="xs:int"/>
                </xs:sequence>
            </xs:complexType>
