1. Choose Bean Shell Form Binder as the Form's Store Binder.

  2. Key in the following code.

    import org.joget.apps.app.service.AppUtil;
import org.joget.apps.form.model.Element;
import org.joget.apps.form.model.FormRowSet;
import org.joget.apps.form.model.FormData;
import org.joget.apps.form.lib.WorkflowFormBinder;
import org.joget.commons.util.LogUtil;
import java.sql.Connection;
import java.sql.SQLException;
import javax.sql.DataSource;

rows.get(0).setProperty("field2", rows.get(0).getProperty("field1"));

new WorkflowFormBinder().store(element, rows, formData);

    In the code above, it will copy the value from form element with id "field1" into "field2".

  3. Save the form.
