Still no takers? :-(

If I have categories A and B, and products X and Y. Initially
category A contains only product X, and category B contains only
product Y.
If I have fetched category A into the cache, then load product Y, and
modify it thusly...
productY.getCategories().add(categoryA);
...and save it, the correct record is inserted into the indirection
table describing the relationship between categoryA and productY.
However, the cached copy of A is not updated with the new
relationship. If categoryA is purged from the cache and
re-materialized, it contains both X and Y in its products collection.
Is this correct behavior or is this a bug? If it is a bug, will it be
fixed before 1.0 final is released?
Thanks...
