[SQLObject] Forcing cache refresh of MultipleJoins

[Edmund L. <el...@in...>]

I have a one-to-many relationship of the form:

class A(SQLObject):
    ...
    things = MultipleJoin("B")

class B(SQLObject):
    ...
    aThing = ForeignKey("A")


If I check what things are in A via something like aObj.things, then 
delete one of the B objects that appears in the list directly via 
bObj.destroySelf(), executing the aObj.things again raises a
SQLObjectNotFound error for the just deleted B instance.

Executing aObj.things a second time works though. So there appears to be 
some kind of cache synchronization issue at play here. Is there some way 
to force an object to refresh it's cached values?
