"Required" Not Working for Multi-Select Field Type

If a multi-select is set to "required" and a selection is not made by the user, an error message does not pop up to prevent the user from proceeding. Instead, the following error message is displayed at the top of the next page.

Warning: implode() [function.implode]: Invalid arguments passed in /home/zygrinsi/public_html/starburst/components/com_jdonation/helper/fields.php on line 426
