using -1 with the tree behavior will undoubtedly break it or at the
very least make the tree behavior report your tree to be invalid. If
you really really want to break the tree behavior I'd suggest you run
recover and then updateAll(array('parent_id' => -1), array('parent_id'
=> null)); Or some other such permutation. Alternatively - why not
capture the conditions used in the model and replace -1 with null. Or
even better since it's obvious that you need to eventually need to
change this, just do it right first time and replace all the -1s with
nulls.
