NSPathControl ClickedPathItem Doesn't Work

Bug Report: FB7484074

Went back to cells for now. Work fine again.

Sorry, but I have problem understanding exactly the question.

What do you mean 'deprecated' cells ? And secretCells.

Could you explain the logic behing and what you try ?

Documentation and compiler warnings flag cells as deprecated for NSPathControl and say to use the "item" methods instead.

Putting a breakpoint near the end of the above code allows expanding local variables to display the contained "_secretCell" for each "item" as shown in the table. My theory is that the "copy" attribute on the item properties gives you items that are useless in determining the array index of the item that was clicked, because none of them match the "clickedPathItem" returned. However, if you look at the "_secretCell" for clickedPathItem, it does match the clicked _secretCell" in the pathItems array. But you don't have programatic access to the secretCells.

A. better solution might be to just return the index of the clicked item.

"Someone might say "just match the titles". That doesn't work, because paths can contain duplicates. Maybe instead of "indexOfObject" in the array, we might be able to write a routine to match a binary equivalent.

This is how I do it and I'm not having any issues, but I'm using double action, not a single action:

-(IBAction)pathControlDoubleClickAction:(NSPathControl*)sender
{
    NSPathControlItem *clickedItem = sender.clickedPathItem;
    NSArray <NSPathControlItem*>*pathItems = sender.pathItems;
    NSURL *clickedURL = clickedItem.URL.filePathURL.URLWithTrailingSlash; //<--Assumes directory, but that may not be the case for your app.
    if (clickedURL == nil)
    {
        return;
   }
      NSURL *lastPathItemURL = pathItems.lastObject.URL.filePathURL.URLWithTrailingSlash;

if ([clickedURL isEqual:lastPathItemURL])
    {
         //Ignore double action if last path item is clicked (may not be what you want in your app).
         return;
     }


    [self _doUpdateUIWithURL:clickedURL];
}

Well I'm back, and this bug has never been fixed in Objective C, and I'm pretty sure it also persists in Swift. The problem is that clickedPathItem is readonly and returns a reference to the clicked item, but pathItems is "copy" and does not contain the clicked item. Copies likely also copy the enclosed secretCells. Both indexOfObject: and indexOfObjectIdenticalTo: return NSNotFound and are therefore useless. While I could try to find the index by comparing titles, that is also useless because URL paths can contain multiple titles that are identical. So far, I have not come up with a workaround. I'm trying to get rid of compiler complaints about using deprecated cells.
