Primefaces extensions DocumentViewer in hyphenated languages

[ei6039]

I use pe:documentViewer for display documents and set 'locale' like pt (pt_pt, pt_br, pt-pt or pt-br) but nothing happens and the actions continues in english. why?

My code is:

Code: Select all

<pe:documentViewer locale="pt" height="#{previewHeight}" value="#{previewComponent.file}"/>
