Subject: Fixing error in OfficeAdsForm: save/remove
X-Git-Url: https://git.gumartinm.name/?a=commitdiff_plain;h=66173690b4e33ac57d599b79d47ca322ecd64af4;p=mobi%2F.git

Fixing error in OfficeAdsForm: save/remove

I did not realize before that while saving or removing objects
in OfficeAds table I had to count on the user's choice and remove
or save all of those objects whiche must not stay in the data base.
