I encountered a problem, when you try to change or assign a picture to a banner in Customer Info -> Promotions it doesn’t work in Oxid 6.0.1 and 6.0.2. I inspected code and found that in previous versions method save() in the class ActionsMain has a line
$oPromotion = \OxidEsales\Eshop\Core\Registry::getUtilsFile()->processFiles($oPromotion);
And this line is missing in 6.0.1 and 6.0.2. I created new project of version 6.0.1 and tried to change banner pic and it didn’t work. Is it a bug?
