I have a page containing a PrimeFaces (2.2.1) Editor component, a Refresh button and a selectOneMenu, whose selection affects the contents of the Editor, as follows:
please try the onchange="window.location.reload();" approach like:
onchange="window.location.reload();"
This works just fine in my environment (GF 3.1.1, PF 3.2) but please be aware that there is the possibility of interrupting some ajax functinality.
Hope this helpes, have Fun!
