Flex Container changes

Hi,

you have pushed new changes in code in repo 2 month ago, point on flexContainer implementation. After few studying days, i have seen that when i try to update a single fcnt option (such as hd_tempe or hd_color), Mobius makes the update for all rows in the fcnt table. Why?

And is there a link where i can study the privileges of using flexContainer with SDT? Thanks all so much!
