Many wsdl parser cannot parse well the prado generated wsdl-s when using an
objectarray as parameter. For example soapui cannot generate the empty
objects. With my modification it seems to be solved. 

Tag: prado-3.1.6.r2699

1. example source:
    /**
     * @param ProductObject[] $ProductsArray
     * @return addOrUpdateProductResults
     * @soapmethod
     */
    public function addOrUpdateProduct($ProductsArray) {
...

Old one:
            <xsd:complexType name="ProductObjectArray">
                <xsd:complexContent>
                    <xsd:restriction base="soap-enc:Array">
                        <xsd:attribute ref="soap-enc:arrayType"
wsdl:arrayType="tns:ProductObject[]"/>
                    </xsd:restriction>
                </xsd:complexContent>
            </xsd:complexType>

With the new one:
            <xsd:complexType name="ProductObjectArray">
                <xsd:sequence>
                    <xsd:element
xmlns:xsd="http://www.w3.org/2001/XMLSchema" name="ProductObject"
type="tns:ProductObject" minOccurs="0" maxOccurs="unbounded"/>
                </xsd:sequence>
            </xsd:complexType>
