Grails createCriteria() used inside Domain classes

Question

Just got to know about the capability of createCriteria() method. Just wanna know that other than applying it on the Controller, is there a way to apply onto the domain classes as well? Probably on its own mapping to a property like:

static mapping = {
      additionalInfo: Page.createCriteria().list()
}

Perhaps you may want to simply create a new field based the target field like the below example:

class myInfo {
    String additionalInfo
    String[] moreInfo  // a transient field

    getMoreInfo(){
        def myresultmap = createCriteria.list{
         // insert any other criteria shenanigans
        }
        return myresultmap
    }
    static transients = ['moreInfo']
}

In a controller return a view like normal with the Domain instance of class MyInfo Then use in view like:

<g:each in="${domaininstancefromcontroller}">
${it.moreInfo[0]
</g:each>

see docs. Hope this helps.
