How do I find out the component that generates this error?

I know what is happening, but I do not know how to isolate the component so I can give it a unique ID.

I am generating a fairly complex form and somewhere along the line, it creates a duplicate component ID. (see error below).

The problem is that I do not know how to identify the component that has the duplicate ID.

If I can find out which component it is, I can generate uinque ID's.

The problem is that neither the page or server errors reference anything directly related to my code, it all appears to be related to the renderer.
