Hi!
Does castor support other types than Collections when using lazy loading
on many relations?
Because as far as I can see the following happens:
A org.castor.persist.proxy.RelationCollection is created to handle the
lazy loading. That class implements Collection.
When the FieldMolder then invokes the set method (which e.g. requires a
Set or anything but a Collection), the invokation fails because of an
illegal argument (collection instead of set).
Did we get anything wrong or is this just not supported?
Thanks in advance!
