[Springframework-rcp-dev] [Spring-JIRA] Commented: (RCP-202) Binding to a superclass should be possible

Geoffrey commented on RCP-202:
------------------------------

A similar bug: the source is an instanceof the targetClass, then no conversion should be done.

For example I got this error:
No converter registered to convert from sourceClass 'class ....OrderParticipantState' to target class 'class java.lang.Enum'
(but if you try myOrderParticipantsState instanceof Enum it says true: emumOrderParticipantState is a subclass of Enum because all enums are).

>     public Class[] getTargetClasses() {
