Re: Problems with groups and static SDOs.

Hi  Chris,
 the code snippet you supplied doesn't compile against the code that I
generated. Person's dog Property is isMany=true so to add a dog you need to
do person.getDog().add(aDog)

Hi,

I'm having a little generation problem with groups. Here's my sample
schema:

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";
targetNamespace="http://www.example.org/Person";
xmlns:person="http://www.example.org/Person";
elementFormDefault="qualified">
    <xsd:element name="Person" type="person:PersonType"></xsd:element>

    <xsd:complexType name="PersonType">
        <xsd:sequence>
                <xsd:element name="Name" type="xsd:string"></xsd:element>
                <xsd:element name="Age" type="xsd:string"></xsd:element>
                        <xsd:group ref="person:AnimalGroup" minOccurs="0"
maxOccurs="unbounded"/>
        </xsd:sequence>
    </xsd:complexType>

    <xsd:simpleType name="Hair">
        <xsd:restriction base="xsd:string"></xsd:restriction>
    </xsd:simpleType>

        <xsd:group name="AnimalGroup">
                <xsd:choice>
                        <xsd:element name="Cat" type="person:CatType"/>
                        <xsd:element name="Dog" type="person:DogType"/>
                </xsd:choice>
        </xsd:group>

    <xsd:complexType name="DogType">
        <xsd:sequence>
                <xsd:element name="Name" type="xsd:string"></xsd:element>
                <xsd:element name="Age" type="xsd:string"></xsd:element>
                <xsd:element name="Breed" type="xsd:string"></xsd:element>
        </xsd:sequence>
    </xsd:complexType>

    <xsd:complexType name="CatType">
        <xsd:sequence>
                <xsd:element name="Name" type="xsd:string"></xsd:element>
                <xsd:element name="Age" type="xsd:string"></xsd:element>
                <xsd:element name="Breed" type="xsd:string"></xsd:element>
        </xsd:sequence>
    </xsd:complexType>

</xsd:schema>

And my code:

        HelperContext context = SDOUtil.createHelperContext();

        PersonFactory.INSTANCE.register(context);
        PersonType person = PersonFactory.INSTANCE.createPersonType();

        person.setAge("30");
        person.setName("Jim");

        DogType dog = PersonFactory.INSTANCE.createDogType();
        dog.setAge("4");
        dog.setBreed("pug");
        dog.setName("chewie");

        DogType[] dogs = new DogType[0];

        person.setDog(dogs);
        person.getDog();

I get the following exception when running either setDogs() or getDogs():

Exception in thread "main" java.lang.ClassCastException:
org.eclipse.emf.ecore.util.FeatureMapUtil$FeatureEList
        at org.example.person.impl.PersonTypeImpl.setDog(

        at Test.anyTest_Static_Person(Test.java:144)
        at Test.main(Test.java:153)


Let me know if you need any more information. Thanks,
