This works fine:

@Model.NodeById(parentNode).DescendantsOrSelf().Where("nodeTypeAlias.Contains(\"Story\")")

Hi Jason,

Give this a try:

@Model.DescendantsOrSelf().Where("!nodeTypeAlias.Equals(\"Archive\")")

Still getting that error.  It's like when I use not (!) then it throws the error.

Hm.  Try posting your script - I tried the above expression and didn't get any error regardless of what I was comparing the nodeTypeAlias to...

Also, is that the full error you are getting?

Model.DescendantsOrSelf("Archive") ... Looks fine to me ... But it's not :-)) Sorry

Use not insteed of ! =>

@Model.DescendantsOrSelf().Where("not(nodeTypeAlias.Equals(\"Archive\"))")

OK, I did a smaller test and both of these methods work.  Thanks guys! 

Unfortunately, that means the problem is elsewhere...

Model.Descendants.Where("NodeTypeAlias == \"externalCollection\" || NodeTypeAlias  == \"individualCollection\"");

any reason why that doesn't work??

nodeTypeAlias :-)

nope still doesn't work

 var allCollectionItems = Model.Descendants.Where("nodeTypeAlias.Equals(\"externalCollection\") || nodeTypeAlias.Equals(\"individualCollection\")");

var allCollectionItems = Model.Descendants.Where("nodeTypeAlias.Equals(\"externalCollection\") || nodeTypeAlias.Equals(\"individualCollection\")");

if(allCollectionItems != null)
    { 
      <ul>
        @foreach (var item in allCollectionItems)
        {
        <li><a href="@item.Url"@cssClassForItem(item)>@item.Name</a></li>
        }
      </ul>
    }

The Where function accepts operators such as equal, contains ect... does anyone have a list of these or know where I could find a list? Would be very handy.

is working on a reply...
