I have a sporadic unmarshalling problem using the following specific mapping
file:

  <class name="test.addrBook.Port" auto-complete="true" >
  </class>
  <!-- Extended class mapping -->
  <class name="test.addrBook.PortExt" auto-complete="false"
             extends="test.addrBook.Port" >
          <map-to xml="Port"/>
  </class>

and my xml data are as follow:

  <?xml version="1.0" encoding="UTF-8"?>
    <Port>
        <name>port1</name>
        <number>12</number>
        <type>3</type>
    </Port>

When i unmarshal the xml data using this mappingg file, sometime
it works and a class PortExt is intanciated, and sometime it does
not work and a class Port is instanciated by error.

I have found a solution which avoid this problem, i have added the field
'map-to xml' in the description of the class Port. This added field is
strictly needless for my application, but solves the problem.

Hereafter, the new mapping solving the unmarsalling problem:
  <class name="test.addrBook.Port" auto-complete="true" >
          <map-to xml="Port_NotUsed"/>
  </class>
  <!-- Extended class mapping -->
  <class name="test.addrBook.PortExt" auto-complete="false"
             extends="test.addrBook.Port" >
          <map-to xml="Port"/>
  </class>

After debbuging in the castor source, i think it might be a bug but i am not
sure ?
Is there anyone to confirm that...
The only aim of this email is to point out this pecular unmarshalling
problem,
and help the users of castor xml.
