Hi,

It seems like when you copy and paste an entire html document into the editor (that already has content), DOM elements in the body are duplicated in the Live Preview. This happens regardless of whether the new body content you paste in is the same or different.

I am running the latest version of Brackets on Mac OS X Mavericks.

Here's a screencap of it:

Thanks :)

I dug into the code a bit and I think I tracked it down to this function

This statement results in null because the new <html> tag gets a new tagID which cannot be mapped to a corresponding <html> tag in the old DOM structure.

So, it fails the if(oldElement) check and executes this. In the function generateChildEdits, it fails this condition, not entering the loop where the delete/insert operation (delete the old html tag with the old tagID and insert the new one) happens. It instead only does the insert operation.

Seems like the problem comes from passing in null as the first parameter into generateChildEdits. But not sure how to fix it though.

solved ... just disable (StaticServer)
go to ... Extension manager >> Default >> disable (StaticServer)
and use an alternative (Autosave) extension then enable (auto save (400 ms))
it will be in (File) after installation
