#28 ElementMap object can't be referenced

[Anonymous]

When an object is stored in a map, it can't be referenced and a CycleException occured.
For example, the following exception occured when executing the test below :

Exception in thread "main" org.simpleframework.xml.strategy.CycleException: Invalid reference 'id1' found

test.xml
--------------------
<?xml version="1.0"?>
<root>

<belements>
<belement name="BElement1">
<aelement ref="id1" />
</belement>

<belement name="BElement2">
<aelement ref="id1" />
</belement>
</belements>
