[b]Description[/b]

When (a) a persisted class has two associated properties of the same type, (b) that type has a proxy, (c) that type has a complex property, only the first association (alphabetically) is eagerly fetchable. If both have an outer-join="true" setting in the mapping, the second is ignored, leading to lazy initialization exceptions.
This is due to how the sql string for the persisted class is constructed (in AbstractEntityLoader.initStatementString). The list of associations that is a parameter there, is constructed by walking the association tree. When walking the association tree, a set of visisted persisters is maintained. The persister for the properties is added to this set when evaluating the complex property of this property. When the visitor wants to visit the second property, the persister is already in the set and the property is not visisted and thus not added to the list of associations and eventually not added to the select statement.
This also leads to unnecessary SELECT statements when loading an object in the described situation where the property is not proxied.
Is this a bug?
