Umb 7.7.6

More curiosity than anything, but why doesn't IsLast() work in this scenario......

var sitePages = Model.Site().Children();
var mainNavList = sitePages.Where(x => x.IsVisible() && x.GetPropertyValue<bool>("includeInMainNav") == true);
var footerNavList = sitePages.Where(x => x.IsVisible() && x.GetPropertyValue<bool>("includeInFooterNav") == true);

<nav>
    <ul>
        @foreach(var page in footerNavList) {
            <li>
                <a href="@page.Url" title="@page.Name" class="active">@page.Name</a>@page.IsLast("", " |&nbsp;")
            </li>
        }   
    </ul>                                                            
</nav>

I've got the effect I wanted in the end with the following but I just wondered why, as I am iterating over a collection of IPublishedContent so IsLast() should work shouldn't it?

var sitePages = Model.Site().Children();
var mainNavList = sitePages.Where(x => x.IsVisible() && x.GetPropertyValue<bool>("includeInMainNav") == true);
var footerNavList = sitePages.Where(x => x.IsVisible() && x.GetPropertyValue<bool>("includeInFooterNav") == true);
var lastItem = footerNavList.Last();

<nav>
    <ul>
        @foreach(var page in footerNavList) {
            string divider = "";
            if(page != lastItem) {
                divider = " |&nbsp;";
            }
            <li>
                <a href="@page.Url" title="@page.Name" class="active">@page.Name</a>@Html.Raw(divider)
            </li>
        }   
    </ul>
</nav>
