below code showing list of action in table. @ bottom of page there button “view” activated when select row in table.

out of box working fine: when select row “view” button activated in 2sc. 

<h:form id="actionlistform">     <p:panel header="#{bundle.listactiontitle}">         <p:datatable id="datalist"                      value="#{actioncontroller.items}"                      var="item"                      rowkey="#{item.idaction}"                      paginator="true"                      rows="10"                      rowsperpagetemplate="10,20,30,40,50"                      selectionmode="single"                      selection="#{actioncontroller.selected}">             <p:ajax event="rowselect"   update=":actionlistform:viewbutton" listener="#{actioncontroller.resetparents}"/>             <p:ajax event="rowunselect" update=":actionlistform:viewbutton" listener="#{actioncontroller.resetparents}"/>             <p:ajax event="contextmenu" update=":actionlistform:viewbutton" listener="#{actioncontroller.resetparents}"/>             <p:ajax event="rowdblselect" onsuccess="document.getelementbyid('actionlistform:viewbutton').click();"/>             <p:column sortby="#{item.idaction}" filterby="#{item.idaction}">                 <f:facet name="header">                     <h:outputtext value="#{bundle.listactiontitle_idaction}"/>                 </f:facet>                 <h:outputtext value="#{item.idaction}"/>             </p:column>             <p:column sortby="#{item.actionlink}" filterby="#{item.actionlink}">                 <f:facet name="header">                     <h:outputtext value="#{bundle.listactiontitle_actionlink}"/>                 </f:facet>                 <h:outputtext value="#{item.actionlink}"/>             </p:column>             <p:column sortby="#{item.identity.name}" filterby="#{item.identity.name}">                 <f:facet name="header">                     <h:outputtext value="#{bundle.listactiontitle_identity}"/>                 </f:facet>                 <h:outputtext value="#{item.identity.name}"/>             </p:column>         </p:datatable>         <p:commandbutton id="viewbutton"   style="visibility: hidden;" icon="ui-icon-search" value="#{bundle.view}" update=":actionviewform" oncomplete="pf('actionviewdialog').show()" disabled="#{empty actioncontroller.selected}"/> </h:form>

problems start when tried limit record showed in table, below modification 

<h:form id="actionlistform">     <p:panel header="#{bundle.listactiontitle}">         <p:datatable id="datalist"                      value = "#budgetcontroller.getallactionbyentity('bob’}"

after modification, when select row, “view” button take @ least 10sc activated. below getallactionbyentity method in class actioncontroller

public list<action> getallactionbyentity(string iduserparam) {   entitymanagerfactory emf = persistence.createentitymanagerfactory("propensionpu");   entitymanager em = emf.createentitymanager();   try {       entity identity = new entity (iduserparam);       allactionbyentity =  em.createnamedquery("action.findallbyentity").setparameter("identity", identity).getresultlist();   }          catch (noresultexception e) {system.out.println (e);} return allactionbyentity; }

and extract of action.java query referenced above:

 @namedquery(name = "action.findallbyentity", query = "select action a.identity = :identity")})

would has idea of reason creating slowness? in case can please me correct mistake?
