This PR fixes the scheduled product page loading issues, which occur when job settings contain arrays, mentioned in https://progress.opensuse.org/issues/166154

example:

I found a bug. The display of multiline fields is now broken:
before

after

Please fix your commit that still says "WIP"

And could you provide a screenshot so we can see how it looks like when one has such "structured variables" on a product?

What you put into the description of the pull request could also be in the commit message details. I don't know how you created your pull request but your git commit messages has only the subject line while the pull request description has more details. Please keep in mind that the github pull request description is only visible on github, the commit can be considered permanent information storage.

I can recommend the tool hub (zypper in rubygem-hub) for easier PR creation. Also, I myself use a script git-pr-last to create a PR with proper description for these simple one-commit PRs:

$ cat $(which git-pr-last )
#!/bin/sh -e
target="${target:-"$USER"}"
git push $target && git show --no-patch --format=%B | hub pull-request -F -

[Martchus]

@b10n1k "calisthenic touches" as in https://en.wikipedia.org/wiki/Calisthenics ? This seems highly unrelated :-)

Sorry but I just noticed that I missed to press the comment button or something in the morning and one of my comments was missing.
