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

[Oliver H. (JIRA) <no...@at...>]

     [ http://opensource.atlassian.com/projects/spring/browse/RCP-202?page=all ]

Oliver Hutchison updated RCP-202:
---------------------------------

    Priority: Minor  (was: Major)

I don't see how this would work.

If the converter worked for all subclasses, how would the conversion from String to a targetClass instance know which subclass is intended?
