Demo: upload file behaves oddly

[markw]

3. Uploading a file behaves counter-intuitively (I would suggest wrongly).

When adding a new resource by uploading a file, I select a file called say create-group.png. I expect the following to happen:

• the pathname of that file is filled in the box;
• nothing is actually uploaded till I hit 'add' (confirming that I've got the right file etc).

Instead of this,

• the file is immediately and, seemingly, irrevocably uploaded;
• the box is filled with a mysterious URL (​https://commondatastorage.googleapis.com/ckan-demo ...)
• the mysterious URL is so long I can't even see the final element, which is my file name.

Have assigned to client team to decide what they want to do about this.
