Required flag not being added to yaml files, resulting in failure to post

[Rings4]

I've created a couple yaml files today and found that the postAdForm.attributeMap[forsaleby_s] flag is not being created nor populated, resulting in ads failing to post. After comparing the yaml files of the ads that I got to post successfully with the ones that failed, I noticed that flag was missing in the failing ones, so I added in the following:

postAdForm.attributeMap[forsaleby_s]: ownr

Now these ads post. I think the yaml creation process needs to be adjusted such that this flag is always present and being populated. Apologies if this was already discussed in another issue.
