Re-populate struts2 checkboxlist data from database

I've a checkbox like

<s:checkbox name="modProcessVO.byWeeklyCal" id="week">Days of the Week</s:checkbox>

and another checkboxlist

<s:checkboxlist list="{'Mon','Tue','Wed','Thur','Fri','Sat','Sun'}" name="modProcessVO.weeklyCal" id="days" />

. When I check the checkbox it's value will store as 'true' otherwise 'false' in database. If it is 'true' then only I'm saving the checked list of data from the checkboxlist. So when I want to modify the data I need to re-populate it back from DB to checkboxlist as checks . I tried by taking the days from db in action class in a list of string called 'wordList' and written in jsp like

<s:checkboxlist list="{'Mon','Tue','Wed','Thur','Fri','Sat','Sun'}" name="modProcessVO.weeklyCal" value="%{wordList}" id="days" />

. But say if 5 values are in that list only 1st one is repopulating to checkboxlist (for eg: wordList contains 'Sun', 'Mon' & 'Tue', only 'Sun' showing as checked). Pls help. Thanks
