[ckan-dev] Error when editing dataset name

[Rachel Knowler]

Hi Nigel,

Thanks for sending that link. The new docs are a lot better than the 
ones I'd been following.

I think the specific problem I had with editing the dataset name was due 
to the name already being editable on the dataset edit page, but I 
somehow didn't realise this because (a) it was labelled URL and (b) you 
need to click an extra button to change it. Everything's working now. :-)

Cheers,
Rachel
