My validator needs to know if it is a full request or an ajax request. In my current solution I check the http request header for the X-Requested-With
element:
I would not rely on http header. Never tried it by myself, but you could do the following:
PartialViewContext pvc = facesContext.getPartialViewContext();
if(pvc.isAjaxRequest()) {
// ...
} else {
// ...
}
Another option is using isPartialRequest()
instead of isAjaxRequest()
I'd that it is a reliable way to check it. This is exactly how for example Django checks for AJAX requests:
def is_ajax(self):
return self.META.get('HTTP_X_REQUESTED_WITH') == 'XMLHttpRequest'
