Accidentally adding a new file to a collection

[richardjpope]

Expected Behaviour

It should be possible to undo the addition of a file when editing a collection

Current Behaviour (for problems)

When editing a collection, if you accidentally click the blue "save and add another file" button rather than the orange "Submit collection for validation" one, it creates and error and it is not posssible to undo.

Steps to Reproduce (for problems)

Provide a link to a live example, or an unambiguous set of steps to reproduce this bug. Include code to reproduce, if relevant

1. Create a collection and add a single file
2. Edit it again and click the blue button
3. Try and click the orange button

I assume this is all taking place on the page where you create a new collection i.e. https://octopub.io/datasets/new, and not on the page for editing a collection i.e. https://octopub.io/datasets/54/edit. Because the latter does provide a delete button in the top right if you click "Save and add another file" accidentally.

That's correct
