[jboss-jira] [JBoss JIRA] Created: (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
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.
More information (stacktraces, actual files used, etc...) is available upon requested.
