Hi
My aim was do Links table changes after editor or admin have submitted link modify
This updates are based on computations with entered data

I tried two ways to save this computations:
made PRE modify_link hook and change $IN->
values to be saved in table during update

But table update happens before PRE modify_link hook
why!!!???

another way:
I triyed use POST modify_link hook
after my table update was executed
I see the foloowing error message popup
'The record you are attempting to modify has changed since you last accessed it'

Please help me reach my aim or explain modify_link hook architechture

Thank you
and table changes are not saved
