Bypass reduceddelta

TDADeltaChange (i.e. table.Delta.change[i]) is separated object and it contains replica of old and new field values.
values in it can be changed w/o changing actual values in table.

so no direct relation between the X and the actual record id of whatever kind
ok got it

thx EvgenyK

i guess
table.Delta.Count
needs to be
table.Delta.Count - 1

yes, ofc
