Set the selection in the controller list of Danish codes

I have a list controller in my Dashcode project, it fetches data from a dynamic source.

After my list controller has loaded its data, I would like to set it by the selected index to 0 - so that information for the first item in the list is displayed. I can’t figure out for my life how to do this. I tried:

function load()
{
    dashcode.setupParts();
    var list = document.getElementById("itemsList");
    //list.setSelectionIndexes(0); // nope
    //list.selectedIndex = 0; // nope
}

No need to write code for this. Edit the properties for the list in the inspector and clear the check box to allow empty selection in the attributes tab. If null selection is not allowed, the first item in the list will be selected when the list is loaded.

Here's an example of selecting a specific item based on its name. For this question, you can just explicitly specify the index 0 - I think Vicente's answer is more appropriate for the question asked, but it might be useful for selecting an item based on a query, etc.



function load()
{
    dashcode.setupParts();

    setSelectedItem();
}

function setSelectedItem()
{
    var itemSource = dashcode.getDataSource("itemsSource");
    var inProgress = itemSource.valueForKey("queryInProgress");

    if(inProgress)
    {
        setTimeout("setSelectedItem()", 200);
    }
    else
    {
        var items = itemSource.valueForKeyPath("content.items")
        for(i=0;i<items.length;i++)
        {
            if(items[i].name.toLowerCase() == "specificItemName")
            {
                document.getElementById("list").object.setSelectionIndexes([i]);
            }
        }
    }
}
