There were duplicate IDs and the `lines` attribute doesn't do anything
for textareas (I guess it was accidentally used instead of the `rows`
attribute; I'm just removing it so the page looks the same way it did
until now).
Even though the `value` field didn't generate duplicate IDs, we're also
changing it because we usually set an element with the `dom_id` of a
record when it contains the whole information about a record, and not
just one piece of it. For instance, in some places we assign this ID to
the table row related to the record.
Currently after each update of any Settings is redirected to the first
tab by default.
As this new tab remote_census_configuation has a lot of fields to fill
in it is a bit uncomfortable to have to go back to the tab after each
update.
- Add hidden field :tag to set current tag value
- After update add tag value to request.referer
- To avoid errors when partial call has not param :tag, add the "define?"
method on hidden_field value.
