Klaus Claszen created JIBX-474:
----------------------------------
Summary: NullPointerException in CodeGen for <xs:list
itemType="xs:int" />
Key: JIBX-474
URL: https://jira.codehaus.org/browse/JIBX-474
Project: JiBX
Issue Type: Bug
Components: CodeGen
Affects Versions: JiBX 1.2.3
Environment: Windows 7, maven 3.0.4, JiBX 1.2.3
Reporter: Klaus Claszen
Attachments: jibx-list-codegen-test.zip
I tried to generate code for the following XSD schema using the
jibx-maven-plugin version 1.2.3:
{code}
<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>
{code}
this results in the following error message
{code}

{code}
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|http://grepcode.com/file_/repo1.maven.org/maven2/org.jibx/jibx-bind/1.2.3/org/jibx/binding/model/BuiltinFormats.java/?v=source]
- 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!
Regards
Klaus
