Strange. Are you sure you have tied the correct method to the correct field? Also double check the contents of your methods. I’ve done some extensive testing with RC3 and can’t reproduce the problem you mention. If you CAN reproduce it please email a small solution that shows the problem to: support@servoy.com with a short description
