[OJB-developers] extents and class hierarchy

[Jakob B. <jbr...@ho...>]

hi ,

while working on a test case for ProductGroup i found that the ProductGroup
only contains articles of classes Article and BokArticle although an query
is successfully executed for CdArticle .
in the repository CdArticle is defined as an extent of Article but it does
not inherit from it, but CdArticle implements InterfaceArticele.

PersistenceBrokerImpl#getCollectionByQuery() does not accept CdArticle for
Article:

// only add candidates with matching class
if (itemClass.isAssignableFrom(candidateClass))
{
tmpMap.add(candidate);
}

i now have two questions:
1) is it acceptable to have an extent definition that does not match the
class hierarchy ?
2) shouldn't the above check be made based on the interface ?
