Slider fails on re-rendered page

[svenmeier]

• Start wiquery demo
• open the slider page
• refresh the page (F5)
• all further Ajax calls fail with StalePageException

This issue is caused by the cached statement in JsScope:

public CharSequence render()
{
    if (statement == null)
    {
        statement = new StringBuilder();
        statement.append("function(");
        statement.append(scopeContext.scopeDeclaration());
        statement.append(") {\n");
        execute(scopeContext);
        statement.append(scopeContext.render());
        closeScope();
    }
    return statement.toString();
}

The rendered callbackScript from SliderAjaxJsScopeUiEvent#execute() contains the render count of the page. Since this is never updated, all following requests are rejected because the page count doesn't match the one of the stored page.

BTW the same error happens with the Tabs-example.
