Hi
Can you use AJAX?
Maybe some AJAX will help.
Just remove the "onchange" values out from your templates and try this
on your page:
@EventListener(targets = "selectCountry", events = "onchange",
submitForm = "quoteForm")
public void changeRegions(IRequestCycle cycle)
{
ResponseBuilder responseBuilder = cycle.getResponseBuilder();
responseBuilder.updateComponent("selectRegion");
}
