Hi

Trying to learn Razor, now that XSLT have been decapitated. I am making a fairly simple navigation and would like to check for the last element in my foreach using the IsNotLast:

@{var footerLinks = Model.NodeById(1214).Children;}
<ul>
@foreach(var lvl in footerLinks)
{
  if(lvl.HasAccess){
    <li>
      <a href="@lvl.Url">@lvl.Name</a>
      @lvl.IsNotLast("|")
      @*@if(lvl != footerLinks.Last()){
        <text>|</text>                              
      }*@
    </li>
  }                  
}
</ul>

@lvl.IsNotLast("|") is giving me an error frontend: Error loading Razor Script green_solutionFooterLinksRZ.cshtml

Cannot invoke a non-delegate type

I can go with the out commented section, wit the if condition, the other option just seems smarter. But what is wrong, why am I getting an error? Site is Umbraco 4.7.1
