Comment 3 for bug 340453

I had thought about plainly overriding the Freeze/Thaw methods the way you're saying, but I wasn't sure of it not having any side effects (like the parent.Freeze calling child's Freeze cycle, but that probably is not the way it works)

It sure would be a better way to provide this fix as a mixin plugged into TransactionOLV not patching ObjectListView's code, since it may be then easier to update the OLV component from upstream.
