Go to "add view", while it is still loading, click the "x" to close the chooser.
The view appears there - but incomplete, without the code checked out in it.
I was just about to report a related issue, but possibly the same.
I interrupted installing the tool because I am impatient and it took longer than 5 seconds, and went to my home page, and then just before I clicked on a dataset it flipped me over to the tool I thought I had cancelled (sql view).
Closing because old. Reopen if you feel strongly.
