Typo : http://framework.zend.com/issues/browse/ZF-8949
and
Recursion : http://framework.zend.com/issues/browse/ZF-8948
I'm not convinced that the recursion fix is 100% as ...
class SingleEntity{
/** @var SingleEntity[] */
public $Entities = array();
/** @return SingleEntity */
public function SingleEntity(){
return new SingleEntity();
}
}
produces types of ...
<xsd:complexType name="ArrayOfSingleEntity">
<xsd:complexContent>
<xsd:restriction base="soap-enc:Array">
<xsd:attribute ref="soap-enc:arrayType"
wsdl:arrayType="tns:SingleEntity[]" />
</xsd:restriction>
</xsd:complexContent>
</xsd:complexType>
<xsd:complexType name="SingleEntity">
<xsd:all>
<xsd:element name="Entities" type="tns:SingleEntity[]" />
</xsd:all>
</xsd:complexType>
<xsd:complexType name="SingleEntity">
<xsd:all>
<xsd:element name="Entities" type="tns:ArrayOfSingleEntity" />
</xsd:all>
</xsd:complexType>
and I've no idea if that is valid.
I'm new with this, so please check this.
Thank you.
