Wt::WidgetSet mode does not handle page refresh
When using WApplication in Wt::WidgetSet mode ivoking Refresh in web browser causes Wt to loose control over the refreshed web page.
To reproduce just run examples\feature\widgetset
On initial page load, Wt application is instantied and Wt widgets are added to the web page.
After refreshing the page in browser, all Wt widgets are gone, the page is only static HTML.
The following error is printed:
[error] "Wt: bogus request: missing signal, discarding"
This makes the Wt::WidgetSet mode unusable, which is a pitty, because it is very productive to create the HTML by hand and only bind to a few DOM elements from Wt code.
