Here,

for (FileItem item : items) {
    if (!item.isFormField()) {
        files.add(item);
    }
}

you're ignoring all form fields, such as the button itself. When continuing such a request, JSF will have no clue that a button was been invoked and thus not queue any action at all.

You need to add an else to collect all form fields in a Map and wrap the request with a HttpServletRequestWrapper which delegates to that map on all getParameterXxx() calls and finally continue the filter chain with the wrapped request. This way JSF will find out that the button was invoked and then queue to the proper action.
