[jboss-jira] [JBoss JIRA] Closed: (JBXB-182) Parse error if a choice is between an element and a sequence which also contains the element

Parse error if a choice is between an element and a sequence which also contains the element -------------------------------------------------------------------------------------------- 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.

More information (stacktraces, actual files used, etc...) is available upon requested.
