    For the web application I'm automating, extended find is disabled,

    I only map the names for the controls I'm interacting with only - e.g. right click on the control and select Map Object

    Select the last option

    I let TC choose the default names, but the last item name I change to something meaningful. Once my objects are all mapped, I then drag them into Aliases mapped object to build a tree structure

     

    I do scripting, and this is the best method I have found, that works for me. I also use TFS as source control.

From your screenshot, you do have name mappings. I'm guessing the references have been broken, which most likely means you'll have to delete and recreate the name mappings again.

 

If you click on Update, on the name mapping, does it update correctly?

 

Unfortunately, there's no other ways of recovering this, if you're not using source control or have Windows file history enabled.
