[Simple-support] CycleException: Invalid reference exception that i dont understand

[Mogens H. <mo...@hv...>]

I am hitting the invalid reference exception when i read an xml. The xml was
created by Simple framework using the CycleStrategy but is fails when I try
to deserialize file.

// This is how I read the file
Strategy cycleStrategry = new CycleStrategy("id", "ref");
Strategy annotationStrategy = new AnnotationStrategy(cycleStrategry);
Serializer s = new Persister(annotationStrategy);
s.read(Project.class, file, false);

// This is the xml I am trying to read

   <autoSave id="17">false</autoSave>
</project>

// This is the exception i get
org.simpleframework.xml.strategy.CycleException: Invalid reference '5' found

But reference 5 should be valid and the type of the <plate id="5">  class is
the same as the one defined in the property <plate ref="5"/>  (otherwise the
serialization would not have defined the reference).

Any ideas would be appreciated
