manually set field which has declare expression?
we have a field which is normally set through the use of a declare expression. However due to some unforseen events we need to fix a few cases in production where we need some way to set the values of this field 'manually'. We tried all sorts of solutions, withdrawing the declare expression etc etc but cannot find a way to set this field and save the workpage through for instance an activity... The field stays read-only because of the declare expression...
Any ideas hints or tips greatly appreciated.
