Am using FormAPI.setRequired("checkboxfieldid").id; in on load event of form to make checkbox field as required dynamically. The checkbox allows multiple values. Am storing the selected values of checkbox in to DB.The statement is setting the field as required but it is not displaying the values that are selected. If am removing the required statement it is displaying the selected values. It is also working when checkbox is of single type and only 1 value is selected. Please help me how to make multivalued checkbox as required dynamically.........
