Combo box set value

hi, im sorry im new at epicor and kinetic
im working on a custom layer for the Start Activity Pruduction Entry window.
i want to set de labor LaborOpr combo box back to 0 or defualt value after a condition.
i been udes row-update with value or expression like 0, “0”, ‘0’ or null but it doesnt work.
i have to solve this on another way?
i need to make some condition when a labor operation is selected so i cant use BPM i think

Welcome to epiusers! I see no one answered your question. I think this is possible, but the row-update only changes the underlying data, not the data on the screen. After you do the row-update, try to refresh the page to see if the value in the operation field changed. If that doesn’t work, you could try using a property-set widget to change the displayed value to match what you set the row to.

Tell us a bit more about why you want to do this. Maybe there is a better way.
Good luck!
