Primefaces extensions DocumentViewer in hyphenated languages not working

Question

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:

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

Answer 1

Solve by changing the locale javascript as it is a bug Primefaces Extension will not find the pt-BR,pt-PT:

<pe:documentViewer value="#{document}" locale="pt" height="800"/>

<script type="text/javascript">

var src = document.getElementsByTagName("iframe")[0].src.replace('#locale=pt','#locale=pt-BR');

document.getElementsByTagName("iframe")[0].setAttribute('src', src);

</script>
