This is now in review at http://codereview.musicbrainz.org/r/1437 and available for testing on http://test.musicbrainz.org/search/edits. Look for the "in subscriptions" option when you choose "artist" or "label" as a search field.

test.mb.org currently redirects to mb.org (!?)

Yes, it is a test server, so I was using it for testing That's now fixed.

Now I get a javascript error "Undefined variable: MB" and "Undefined variable: $"
(opera 11.50 1074 winXP)

Thanks, I did a sloppy job pushing this update out. Should be working now

Concerning this, I think it is missing the opposite "is not in my subscription".

Now a little bit off topic but I have very much difficulty to let's say select editor=jesus2099 AND subscribed artist for instance :

1. I click the select, then click the Editor options
2. Some fields appear but the select re-opens
then sometimes :
3a. I click the text appeared field, then the select gets blank
or
3b. I click the text appeared field, then the select doesn't get blank but after search submit, this line disappeared and found no edits
or 3c. I click the text appeared field, then the select doesn't get blank but after search submit, I get error page

etc.

The opposite is a separate ticket, and I'd like to keep it that way as it's quite a tricky problem. I'll look at your other problems now, thanks for testing

The exception you caused should now be fixed. The others I think are unrelated problems

Sorry I might be total moron.
I strived a little to achieve my edit search because of the mentionned bug on select that gets re-open and gets reset.
But I managed to have these displayed :

Show me edits that match all of the following conditions:
Editor is jesus2099
Artist in my subscriptions
Created after 2011-07-01

And that eventually "Found 0 edits". Which can't be true.

Have you checked you have any subscriptions? test.musicbrainz.org does not currently have private data loaded, so you'll need to subscribe to something first. It's a bit awkward I know, hopefully the next time we reload data we can load the private data too!

Thanks dude, it works great indeed, I can say I'm a moron, no subscriptions !
Have you ever heard of the other problem I described (1, 2, 3a, 3b) or I open a new ticket if not ?

It sounds like it's all related to the autocomplete JS for editor search, so I think that's a different issue.
