@samuelkong 
As the solution for this ticket is to get the option values manually instead of using the definition in the aui select tag.
So the option values "0" can be added at first.
I got the "priefixId" according to the aui select tag definition.And it calls ParamUtil.
Please see line 50 in portal-web/docroot/html/taglib/aui/select/start.jsp
