jsf - Wrong values in <p:rowExpansion> and empty values in <p:cellEditor> on scolled page when using <p:dataTable lazy="true" liveScroll="true"> -

i using jsf 2.2 primefaces 4.0. have <p:datatable> live scrolling, lazy loading, row-expansion , cell-editing, etc.

<p:datatable     id="dtatable"     selection="#{cont.selectedarray}"     resizablecolumns="true"     draggablecolumns="true"     var="datamodel"     value="#{cont.yieldbondsmodel}"     editable="true"     editmode="cell"     selectionmode="multiple"     rowselectmode="add"     scrollable="true"     scrollheight="650"     rowkey="#{modeld.id}+#{model.name}"     rowindexvar="rowindex"     filterevent="enter"     styleclass="screenscrollstyle"     scrollrows="25"     livescroll="true"     lazy="true"     rows="50"     filteredvalue="#{cont.filteredmodel}"     widgetvar="dt4" >     <p:rowexpansion>         <h:panelgrid id="display" columns="2" cellpadding="4" style="width:300px;" styleclass="ui-widget-content grid">             <f:facet name="header" styleclass="datatableheader">other data</f:facet>             <h:outputtext value="id " />             <h:outputtext value="#{datamodel.id}"/>             <h:outputtext value="name" />             <h:outputtext  value="#{datamodel.name}" />         </h:panelgrid>     </p:rowexpansion>      <p:column width="15">         <p:rowtoggler />     </p:column>      ... </p:datatable> 

on first page works charm. once scroll down, data getting lazy-loaded fine, has problems during row-expansion , cell-editing:

1. in row-expansion, getting wrong values. maybe overlapped values other row.

2. cell-editing not working. once edit cell, values not getting displayed in cell-editor. have checked in firebug, there no value in <h:outputtext> confirmed generated html <div class="ui-cell-editor-output" style="display: none;"></div>. can see, there no value inside div.

the backing bean @sessionscoped.
