jsf 2 - Primefaces Chart labels not showing in nested tabview -

i have page nested tabview , :

<p:tabview dynamic="true" id="tabview">     <p:tab title="tab1">         <p:tabview dynamic="true" >              <p:tab title="subtab1" >                // charts : linechart , piechart ...                // labels working             </p:tab >              <p:tab title="subtab2" >                // charts : linechart , piechart ...                // !! labels not working !!             </p:tab>          </p:tabview>     </p:tab>      <p:tab title="tab2">        // charts : linechart , piechart ...        // labels working     </p:tab> </p:tabview> 

so problem labels not working in 'subtab2' , if switch 'subtab2' , 'subtab1' labels work in 'subtab2' , not in 'subtab1'.

in 'tab1' , 'tab2' no problem !

i'm working primefaces 5.1.

the same code working in pf 5.2 .

with pf 5.1 , make work, change dynamic attribute false in second tabview.
