Matt Wringe commented on JBXB-182:
----------------------------------
Ok, I am going to attach a file that contains a very simple test case for this situation. This is a very simple test and doesn't even include a metadata class for the xml file.
The tar.gz contains a simple file that sets up an unmarshaller and tried to unmarshall an xml file (test.test.App) as well as a simple xml (test.xml) file and a simple xsd file (test.xsd).
Its setup as a maven project, so all you need to do to build and run the application is:
mvn package exec:java -Dexec.mainClass="test.test.App"
The way the project is setup right now it will fail, to make it run without failing either uncomment the <foo> option or remove <bar> in test.xml.
StackTrace:
org.jboss.xb.binding.JBossXBException: Failed to parse source: Requested element {file:///tmp/test.xsd}bar is not allowed in this position in the sequence. The next element should be {file:///tmp/test.xsd}foo

> Key: JBXB-182
> URL: https://jira.jboss.org/jira/browse/JBXB-182
> Project: JBoss XML Binding (JBossXB)
> Issue Type: Bug
> Environment: JBoss AS5, JBossXB 2.0.0.GA
> Reporter: Matt Wringe
> Assignee: Alexey Loubyansky
> Fix For: JBossXB-2.0.1.Beta2

> Attachments: test-schema.tar.gz

> JBossXB fails to parse an xml file if the xsd contains a choice between an element and a sequence which also contains the element.
> For example, in the follow the choice should allow the option between specifying A and then B, or just B
> <choice>
> <sequence>
> <element name="A"/>
> <element name="B"/>
> </sequence>
> <element name="B"/>
> </choice>
> But, if an xml file used contains just B, an exception will be thrown saying that B is in the wrong order for the sequence. The expected result would be that it should work since just having B is valid.
> Part of the actual xsd file (http://java.sun.com/xml/ns/portlet/portlet-app_1_0.xsd) in question:
> <choice>
> <sequence>
> <element name="resource-bundle" type="portlet:resource-bundleType"/>
> <element name="portlet-info" type="portlet:portlet-infoType" minOccurs="0"/>
> </sequence>
> <element name="portlet-info" type="portlet:portlet-infoType"/>
> </choice>
> Part of the stacktrace thrown when a portlet-info element is declared in an portlet.xml file without resource-bundle:
> Caused by: org.jboss.xb.binding.JBossXBRuntimeException: Requested element {http://java.sun.com/xml/ns/portlet/portlet-app_1_0.xsd}portlet-info is not allowed in this position in the sequence. The next element should be {http://java.sun.com/xml/ns/portlet/portlet-app_1_0.xsd}resource-bundle

> Note: when using other tools, the xsd file validates as a proper xsd file, and the xml file used properly validates against the specified xsd.
