jsf - Is there any FacesConfirm class like FacesMessage -

is there facesconfirm facesmessage? need pass confirmation dialog instead of message.

facesmessage msg = new facesmessage("the version " + version + " exists.", " import data replace existing data."); facescontext.getcurrentinstance().addmessage(null, msg); 

no. render <script> conditionally.

<h:panelgroup rendered="#{not empty bean.confirmmessage}">     <script>confirm('#{bean.confirmmessage}');</script> </h:panelgroup> 

or use 3rd party jsf component library uses similar mechanism, such primefaces' <p:confirmdialog>.
