Issue while generating bindings

[lucabotti]

While generating bindings with the following command:

xsdata generate -r xsd --package generali.service-models

I receive the following error

xsdata.exceptions.CodeGenerationError: Enumeration class with a complex extension.

JAXB (Java API) manages the xsd , and I submitted the same to w3c org validator. Any way to get more details about the error?

Hey @lucabotti can you provide the schema please or a sample?
The error refers to a case I thought it was impossible to occur.

Here is the issue

	<xsd:complexType name="GenderCodeType">
		<xsd:simpleContent>
			<xsd:restriction base="cdt:CodeType">
				<xsd:enumeration value="Male" />
				<xsd:enumeration value="Female" />
				<xsd:enumeration value="Neutral" />
				<xsd:enumeration value="Other" />
			</xsd:restriction>
		</xsd:simpleContent>
	</xsd:complexType>

	<xsd:complexType name="CodeType">
		<xsd:simpleContent>
			<xsd:extension base="xsd:token">
				<xsd:attribute
					name="listID"
					type="xsd:token"
					use="optional">

				</xsd:attribute>
				<xsd:attribute
					name="listAgencyID"
					type="xsd:token"
					use="optional">

				</xsd:attribute>
				<xsd:attribute
					name="listAgencyName"
					type="xsd:string"
					use="optional">

					</xsd:annotation>
				</xsd:attribute>
...
...
...
			</xsd:extension>
		</xsd:simpleContent>
	</xsd:complexType>

The gender code type is clearly an enumeration and the base class is not. Jaxb translates that to

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "GenderCodeType")
public class GenderCodeType
    extends CodeType
{


}

Which practically eliminates the enumeration, I am not so sure if this is the correct way, do you have any xml samples that go with that suite?

[tefra]

I thought this scenario was not allowed or something, since none of my 25k samples have it. The easiest approach would be to mimick xjc but I am not so sure that's correct either, that's why I would like some xml samples to see if there is a better alternative.

Hi,

Pyxbgen (old, I know) managed the enumeration with the attached file. I have same examples of Agreement I attach.

Hey @lucabotti thanks for reporting this issue, interesting suite, I added it in the samples.

A fix is on master, it's not really what I wanted but it follows jaxb practise. The issue is about restricting complex/simple content types with specific enumeration values. Ideally I wanted to be able to something like this, but mypy doesn't allow for that.

class Foo:
    value: str

class Bar(Foo):
    value : SomeEnumeration
   

class SomeEnumeration(Enum):
    A = 1
    B = 2

So for now the end result will be like this, I will try to find a solution to somehow keep the enumeration values either as python Literals or try to make enumerations to play nicely with mypy but that will require some more time.

class Foo:
    value: str

class Bar(Foo):
     pass

I opened a new issue to follow up with a proper, if possible, solution in the future #663

HI Tefra,

thanks. Will check everything.
