I'm using the Xpath checkboxlist to basically categorize my pages. In my case I'm categorizing news items into housing associations. This is so I can view news relevant to a housing association. I can't use tags as they are being used in addition to this.

Where I'm listing my news items I want to be able to select news items that have a housing association ticked but I can't ever seem to get a value for the Xpath checkboxlist. Here is my code:

var NewsItems = Model.Descendants("NewsItem").OrderBy("postDate desc");
var housingAssociation = Model.AncestorsOrSelf().Where("NodeTypeAlias == \"HousingAssociation\"")[0]         
NewsItems = NewsItems.Where("housingAssociation.Contains(\"" + housingAssociation.Id + "\")");   

However when I debug the housingAssociation property of an individual news item is always empty.

Has anybody else has this issue or know how I can resolve?

Thanks
