[SQLObject] InheritableSQLObject and MultipleJoins

[Jonathan W. <jwi...@to...>]

I've got a three level inheritance model that looks a little like this:

class Node(InheritableSQLObject):
	parent = ForeignKey('Node', default = None)
	children = MultipleJoin('Node', joinColumn = 'parent_id')

class ContentNode(Node):
	content = StringCol(default = None)

class Page(ContentNode):
	comments = MultipleJoin('Comment', joinColumn = 'parent_id')

class Comment(ContentNode):
	pass

And create some test data like so:

thePage = Page(content = 'Page 1')
theComment = Comment(content = 'Comment 1')
theComment.parent = thePage

When I print the children of the page, everything is correct (i.e.  
the one comment is listed)

print thePage.children

When I try to print the comments of the page, I get an error:

print thePage.comments

Is MultipleJoin not smart enough to understand instances of  
InheritableSQLObject? And if not is this behavior a bug that will be  
fixed in the future?
