Re: [jibx-users] choice elements

[Dennis Sosnoski]

For now the best you can do is make them all optional - which means you 
won't get an error if none or more than one are present in the XML, but 
at least will handle the case of proper XML input. <xs:choice> does seem 
worth supporting directly, and I'll enter an enhancement item to add 
support for this in beta 4. That's not a guarantee it'll be there, but 
I'll at least look into it.

I have an element defined as follows:
<xs:complexType name="TType">
        <xs:choice>
                <xs:element name="primitiveType" type="TPrimitiveType"/>
                <xs:element name="dataType" type="TDataType"/>
                <xs:element name="activityType" type="TActivityType"/>
                (...)
        </xs:choice>
</xs:complexType>
Other binding frameworks (JAXB, and from what I understood a a previous 
post in this list, Castor as well) usually generate classes with a 
structure like this:
class Type
{
	private PrimitiveType itsPrimitiveType;
	private DataType itsDataType;
	private ActivityType itsActivityType;
	(...)
}

with only one of these fields having a non-null value.

But I have a class like this:
class Type
{
        private TypeStrategy itsStrategy;
}
PrimitiveType, DataType and ActivityType... implementing TypeStrategy.

I did not find a way to define a mapping for this kind of element. Right 
now, I am solving it with a custom marshaller/unmarshaller. This is not 
complicated at all, but I would prefer to avoid that.
Did I miss something and is there already a way to define such a binding 
in xml?
Or is it planned to support that kind of bindings?
