I didn't mean its wasting time at this point. I just want to express that its hard to implement that solution in one or two weeks to walking into 4.6 as an exception. Note I know this feature is still not accepted as an exception to 4.6 right now so I'm making an assumption. > reviewing all the previous versions, I don't see a point in wasting > even more time on working out details of an approach that's getting > too complex/ugly already anyway. Here I'm trying to seek such a kind of two-steps approach if possible. Thanks Tiejun
