jsf - MyFaces: all pages throw duplicate id error after enabled partial state saving -

in jsf 2.2 project primefaces (currently latest: 5.1) have had problems <p:fileupload>. in multi upload scenario randomly selected files not uploaded. problem solved enabled partial state saving (pss) in web.xml:

<context-param> <param-name>javax.faces.partial_state_saving</param-name> <param-value>true</param-value> </context-param>

now after enabling pss, pages throw duplicate id exception (although there no duplicate0. have crud pages <p:datatable> , binding view-scoped beans. when switch mojarra duplicate id errors gone, reasons want work myfaces. there workaround? bug myfaces.
