I have a custom application that uses the Cardboard object to display portfolio items. We had been using a custom attribute for Kanban state but in the latest release Rally added a standard attribute of a Portfolio Item called "State" which was basically doing what our custom attribute did. The problem is while the Cardboard object will take this attribute as the parameter to build the columns on it will never display any data. The columns all appear empty. I noticed this attribute is different then previous simple drop lists as it has two different options "Theme" and "Feature". Perhaps this works differently and Cardboard doesn't query correctly when passed this type of drop down??? Here is the simple version of the call:

        var dropdownAttribute = "State";
    if (stateDropdown !== null) {
        dropdownAttribute = stateDropdown.getValue();
    } 
    var cardboardConfig = {
         types: ["PortfolioItem", "HierarchicalRequirement", "Feature"],
         attribute: dropdownAttribute,
         fetch:"Name,FormattedID,Owner,ObjectID,ClassofService",
         query : fullQuery,
         cardRenderer: PriorityCardRenderer
    };

    if (cardboard) {
        cardboard.destroy();
    }
    cardboard = new rally.sdk.ui.CardBoard(cardboardConfig, rallyDataSource);
    cardboard.display(dojo.body());

The new State field is actually a reference to a new Domain Object. We added the object so that we could give each type of Type of Portfolio Item different Kanban States.

What you are seeing is the complete list of all States for all types of Portfolio Item (Theme Feature).

If you want to recreate your current App you would need a new custom field on Portfolio Item and Hierarchical Requirement that has a name other than State. At this time Hierarchical Requirement does have a reference to the new State object but that is something we have plans to explore in the future.
