WhereUsed not showing all results unless clicking refresh

Question

I am writing a small GUI Extension to get the WhereUsed list from Tridion and have some related posts here and here.

I created some sample content, linked them together (component links) and it appears in my GUI Extension and the WhereUsed window from the Component. Went to lunch, came back, list is empty. But, also when I select the WhereUsed button in Tridion 2011 SP1, it's also empty. Then, I select the 'refresh' buton on the popup and the WhereUsed items are back - but not in my GUI Extension.

I'm using the special callback fom Jaime's post here . But, is there another magic method I'm missing to reload the list?

I'm now thinking to use the Core Service to do my WhereUsed bidding for me instead of the Anguilla framework.

I think you need to load the item in question too. For example, if you do a "where used" in an item, call the load method item.load(true), in the same way you do for the list (in my previous post). You will need the item to be loaded in order to access its information. Something like this:

var item = $models.getItem("tcm:1-234");
function onItemLoaded{
        $evt.removeEventHandler(item, load, onItemLoaded);
    ShowWhereUsed(item.getId(), ["16"], ["tcm:1-235-8"]); //Assuming this is the function I posted in my previous posts
}

if(item.isLoaded()){
    onItemLoaded();
}else{
    $evt.addEventHandler(item, "load", onItemLoaded);
    item.load(true);
}

Note: this is an educated guess. Another reason for the "disappearance" of the list might be browser-cache-related.
