how to count instances in each statement in Grails?

Status domain has many like
like belongs to user and status
user has many status and like

I need to show count of likes a status has.

 <g:each in="${statusInstanceList}" status="i" var="statusInstance">
 ${fieldValue(bean: statusInstance, field: "statusMessage")}

 <g:each var="likeInstance" in="${statusInstance.like}">
   ${likeInstance.count()} //this is the where likes should be counted via dynamic finders
 </g:each>

 </g:each>

Also please suggest if I am doing this the right way. If not please put me on to the right track.

${statusInstance.like?.size()} should give the number of likes per status.

......
<g:set var="likesSize" value="${statusInstance.like?.size()}"/>
<g:each var="likeInstance" in="${statusInstance.like}">
   $likesSize
</g:each>
.......

Makes sense?
