timezone - How to display Selected option Of timeZoneSelect Tag in grails -


when creating customer timezone, timezone have value. when show timezone ,i want display selected option.

for example, want display sst, samoa standard time -11:0.0(selected option) rather pacific/midway(value).

class customer {

    static constraints = {     }     string name     string timezone }

in create.gsp: 

<div class="fieldcontain ${haserrors(bean: customerinstance, field: 'timezone', 'error')} ">     <label for="timezone">         <g:message code="customer.timezone.label" default="timezone" />      </label>     <g:if test="${customerinstance?.timezone}">          <g:timezoneselect name="timezone" value="${timezone.gettimezone(customerinstance?.timezone)}" />     </g:if>     <g:else>          <g:timezoneselect name="timezone" value="${customerinstance?.timezone}"  />     </g:else> </div>

in show.gsp:

<span class="property-value" aria-labelledby="timezone-label"><g:fieldvalue bean="${customerinstance}" field="timezone"/></span>

 def show(long id) {         def customerinstance = customer.get(id)         if (!customerinstance) {             flash.message = message(code: 'default.not.found.message', args: [message(code: 'customer.label', default: 'customer'), id])             redirect(action: "list")             return         }          def date = new date()         timezone tz = timezone.gettimezone(customerinstance.timezone);         def shortname = tz.getdisplayname(tz.indaylighttime(date), timezone.short);         def longname = tz.getdisplayname(tz.indaylighttime(date), timezone.long);         def offset = tz.rawoffset;         def hour = offset / (60 * 60 * 1000);         def min = math.abs(offset / (60 * 1000)) % 60;         def timezone= shortname+", "+longname+" "+hour+": "+min         [customerinstance: customerinstance,timezone:timezone]     }
