Hi!
In my opinion, the following issue is a bug. Do you agree?
Here is a minimal example:
The following schema is used by the SourceGenerator without additional
mapping. That works fine. Read on after the schema...
----snip example.xsd-----
<element name='report'>
<complexType>
<sequence>
<element ref='t:A'/>
<choice>
<element ref='t:B'/>
<element ref='t:C'/>
</choice>
</sequence>
</complexType>
</element>
<element name='A'>
<complexType>
</complexType>
</element>
<element name='B'>
<complexType>
</complexType>
</element>
<element name='C'>
<complexType>
</complexType>
</element>
----
Now, if i try to unmarshal the following invalid document, a
StackOverflowError is thrown.
---document---
<A>
</A>
<B>
</B>
<C>
</C>
-----
Here's the Error
java.lang.StackOverflowError
at
org.exolab.castor.xml.util.XMLFieldDescriptorImpl.getFieldName(XMLFieldDescriptorImpl.java:441)
at
org.exolab.castor.xml.util.XMLFieldDescriptorImpl.equals(XMLFieldDescriptorImpl.java:364)

org.exolab.castor.xml.UnmarshalHandler.startElement(UnmarshalHandler.java:1388)
at
org.exolab.castor.xml.UnmarshalHandler.startElement(UnmarshalHandler.java:1626)
...
The last line is repeated may times (loop).
Interessting: The problem ist correctly handled (exception with nice error
message), if you drop element A from the schema and document...
Best regards
Henning
