[jboss-jira] [JBoss JIRA] Closed: (JBXB-104) Improper marshalling for sequence of choices

Alexey Loubyansky closed JBXB-104.
----------------------------------

    Resolution: Rejected
      Assignee: Alexey Loubyansky

The sequence element defines a sequence of particles that can appear in the content. In your case, it's only one choice. Since the choice is not repeatable and the sequence is not repeatable, the result you posted is expected. But actually throwing an exception would probably be the right thing to do if there were more values to marshal.

>             Project: JBoss XML Binding (JBossXB)
>          Issue Type: Bug
>         Environment: JBoss 4.2.0 with bundled jboss-xml-binding.jar on Windows XP, SUSE with 1dk 1.5.11

> When XML Schema includes <choice> nested in <sequence> element, MarshallerImpl serializes only the first element, ie.
> <xs:complexType name="testType">
> <xs:sequence>
> <xs:choice>
> <element name="el1" type="xs:string" minOccurs="0" nillable="true" />
> <element name="el2" type="xs:string" minOccurs="0" nillable="true" />
> <element name="el3" type="xs:string" minOccurs="0" nillable="true" />
> <xs:choice>
> </xs:sequence>
> </xs:complexType>
> For this schema definition, the serialized output for object containing all 3 elements would be only:
> <elementOfTypeTestType>
> <el1>test</el1>
> </elementOfTypeTestType>.
> In my opinion it is not proper handling of the mentioned type. The reason for this behavior lies in method responsible for marshaling elements nested in choice group. It returns after properly marshaling the first element. Instead it should first check the choice element's parent and return only if the parent is not sequence element.
> This bug exists also in the trunk revision of JBoss XML Binding.
