Description:
A few errors, all related to creating a "synthetic" reverse DbRelationship:

1. When creating a reverse reflexive relationship (relationship to itself), the following exception is thrown:

java.util.ConcurrentModificationException

        at java.util.TreeMap$EntryIterator.next(TreeMap.java:1033)

        at org.objectstyle.cayenne.modeler.action.CayenneAction.actionPerformed(CayenneAction.java:184)

2. When there are more then one one-way incoming relationship for a given entity:

java.lang.IllegalArgumentException: Attempt to insert duplicate key. [key 'toVirtualKioskTypeReverse', parent 'VirtualKioskType', child 'toVirtualKioskTypeReverse']
