same is true not only for the description. I put it here to avoid duplicate issues (presumingly the same reason):

when campaign is present:

• the capture date is not extracted automatically but has to be set manually
• the file name field is empty (without campaign it shows the name selected for upload)
• the UW does not extract data from EXIF any more (descr, coordinates)
• when uploading more than a single file, only one of those files is shown in the Description step
• thumbs are not displayed in the description step

(I checked this differences against the case when not using a campaign)

I think the issue reported here has the same root cause: https://commons.wikimedia.org/wiki/Commons:Upload_Wizard_feedback#Copying_information

There are no regular deployments next week due to WMF All Hands / Dev Summit, so I'm going to schedule this for a SWAT deployment.

I get the following error in the JS console (using Chrome):

Seems like a caching issue, as that code (items[ i ].initialiseUls();) should no longer be in uw.DescriptionsDetailsWidget.js.

@kaldari any idea how that might happen?

Due to last week's dev summit & this week's releng offsite, MW deployment train hasn't run & this fix has not yet gotten deployed.

Ignore above; I read over past history in this ticket & @matmarex had scheduled it for deploy. Figuring out why it's not there anymore...

I don't think it's just a caching issue, it appears the patch I've gotten deployed has been thoroughly undeployed.

• As noted, https://commons.wikimedia.org/w/load.php?....... is serving the old code (containing items[i].initialiseUls()).
• https://commons.wikimedia.org/w/extensions/UploadWizard/resources/details/uw.DescriptionsDetailsWidget.js also has the old code (containing items[ i ].initialiseUls()), which rules out ResourceLoader caching issues (and I really haven't seen any in a couple years at least, btw)
• https://commons.wikimedia.org/wiki/Special:Version says it has Upload Wizard version 65d8d40, which is the commit preceding my patch.

It appears that the change got in, but the wrong file ended up being synced (uw.DescriptionDetailsWidget.js (singular) instead of uw.DescriptionsDetailsWidget.js)

Seems to work now, first tests are promising! Will start uploading a few pictures to get a better overview.

@Atsirlin could you have a look and see if your problem is now solved? @Braveheart any further update?

@Cparle: yes, our problem has been resolved. Thank you!

@Cparle Yes, works again for campaigns, thanks! :-)
