jsf - JSF2 + Primefaces : DataTable lazy loading issue -

i guess, java code proper, records not showing on datatable.

please check below code. dont know made mistake.

.xhtml

 <p:datatable value="#{userdetaillist.userdatalist}" var="user" rows="5"                              paginator="true" lazy="true"                              paginatortemplate="{rowsperpagedropdown} {firstpagelink} {previouspagelink}  {currentpagereport} {nextpagelink} {lastpagelink}">                          <p:column headertext="no">                             <h:outputtext value="#{user.id}"></h:outputtext>                         </p:column>                          <p:column headertext="user name">                             <h:outputtext value="#{user.username}"></h:outputtext>                         </p:column>                        </p:datatable> 

.java

@postconstruct     public void init(){         // +getter , setter         userdatalist = new lazydatamodel<userdetail>(){              private static final long serialversionuid = 1l;              @override             public list<userdetail> load(int first, int pagesize, string sortfield,                     sortorder sortorder, map<string, string> filters) {                  return lazydatamodelcom.getresultlist(first, pagesize, sortfield, sortorder, filters);             }         };     } 

getresultlist

public list<userdetail> getresultlist(int first, int pagesize, string sortfield, sortorder sortorder, map<string, string> filters) {         session session = hibernateutils.getsession();          criteria criteria = session.createcriteria(userdetail.class);         criteria.addorder(order.asc("id"));          (map.entry<string, string> entry : filters.entryset()) {             if (entry.getvalue() != null) {                 criteria.add(restrictions.ilike("id",                         "%" + entry.getvalue() + "%"));         }         }          criteria.setmaxresults(pagesize);         criteria.setfirstresult(first);           return criteria.list();      } 

getresultlist method return proper value, debug it. think problem in userdatalist.

your lazydatamodel implementation not setting rowcount. should like:

public void init(){     // +getter , setter     userdatalist = new lazydatamodel<userdetail>(){          private static final long serialversionuid = 1l;          @override         public list<userdetail> load(int first, int pagesize, string sortfield,                 sortorder sortorder, map<string, string> filters) {             userdatalist.setrowcount(...);             return lazydatamodelcom.getresultlist(first, pagesize, sortfield, sortorder, filters);         }     };     userdatalist.setrowcount(...); } 

pay attention rowcount feeded number of rows before pagination after filtering.

see this answer containing working example (with difference uses jpa criteria api instead of hibernate criteria):
