Description

I tried to generate code for the following XSD schema using the jibx-maven-plugin version 1.2.3:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://foo.bar"
	elementFormDefault="qualified" targetNamespace="http://foo.bar">

	<xs:simpleType name="idList">
		<xs:list itemType="xs:int" />
	</xs:simpleType>

	<xs:complexType name="request">
		<xs:sequence>
			<xs:element name="time" type="xs:dateTime" minOccurs="0"
				maxOccurs="1" />
		</xs:sequence>
		<xs:attribute name="knownIds" type="tns:idList" />
	</xs:complexType>

</xs:schema>

this results in the following error message

If I change the xs:list itemType to string (<xs:list itemType="xs:string" />) everything works well.

If I use other types (e.g. "xs:double") I get an "Internal error - invalid list type" although the type seems to be supported (I looked at BuiltinFormats.java - not sure if this is the right place).

So my main issue is to get <xs:list itemType="xs:int" /> working in code generation but I also wonder what list types are supported.

Thanks for any help!

Klaus
