    Take() not working with DynamicNode

    Can someone explain why Take() isnt working here ? 

    var SpecialOfferFdr = @Model.AncestorOrSelf(2).Descendants("v").Where("Visible").Items;

    foreach(dynamic t in SpecialOfferFdr.Take(1)){ 
            if(t.Level == 4){
            @t.Name
            }
}

    This didnt work either 

    var SpecialOfferFdr = @Model.AncestorOrSelf(2).Descendants("v").Where("Visible").Take(1).Items;

    foreach(dynamic t in SpecialOfferFdr){ 
            if(t.Level == 4){
            @t.Name
            }
}

    Hi Stephen,

    Well when i make use of Take(2) here

    var SpecialOfferFdr = @Model.AncestorOrSelf(2).Descendants("v").Where("Visible").Take(2).Items;

    foreach(dynamic t in SpecialOfferFdr){    
           if(t.Level == 4){                                                                                                                      @t.Parent().Name
              }
     }

    I dont get any results,.

    And if i make use of this

    foreach(dynamic t in SpecialOfferFdr.Take(2)){    
           if(t.Level == 4){                                                        
                @t.Parent().Name                    
             }
     }

    I get an error when rendering the script

    In the second case that is because SpecialOfferFdr is obtained from DynamicNodeList.Items so it's an IEnumerable<DynamicNode>... and .Take(2) is an extension method of IEnumerable<T>... trouble is, because Model is dynamic, SpecialOfferFdr is dynamic, and extension methods don't run on dynamics. If you do:

    IEnumerable<DynamicNode> SpecialOfferFdr = Model.....Items;
    foreach (dynamic t in sof.Take(2)) { ... }

    It should work because then SpecialOfferFdr is not a dynamic but explicitely an IEnumerable<T> and the Take() extension method works.

    As for why the first case does not work... can't tell...

    List<DynamicNode> 
    IEnumerable<DynamicNode>
