gsp - Grails pagination not working -

i've been week trying fix pagination problem, no results,

i have in controller

    patientcontroller{     def show(long id) {     def patientinstance = patient.get(id)     if (!patientinstance) {         flash.message = message(code: 'default.not.found.message', args: [message(code: 'patient.label', default: 'patient'), id])         return     }        def historyinstance = history.findallbypatient(patientinstance)     def total = historyinstance.size()       [historyinstance: historyinstance,patientinstance: patientinstance,historyinstancetotal: total]       } } 

and have code on view

    <g:each in="${historyinstance}" var="historyinstances" status="i">       ...     </g:each>      <div class="pagination">         <g:paginate  total="${historyinstancetotal}"/>     </div> 

i used params, max on <g:paginate>, tried no result shows whole set of history in view.

you need pass params finder you're using, otherwise won't know how paginate. <g:paginate> tag displaying pagination links, not performing pagination. total need use countby because result set limited current page of results.

def historyinstance = history.findallbypatient(patientinstance, params) def total = history.countbypatient(patientinstance)
