Dear all,
This topic just so that you know there is a UserVoice open for voting to make it so WF variables can be cononected to fields in task forms so that to remove the tedious task of setting all default values and retrieving all potentially edited fields after each task by having form controls assiociated with a WF variable : https://ideas.nintex.com/ideas/CNV-I-156
Would save us developpers precious minutes that add up to hours and days.
