We've a couple of cleanup microflows which are deleting objects older than x days. One of these microflows is hanging on delete of the objects. So I decided to do the remove in a java-action instead of looping over each object and then delete one by one. My problem is that I need the java-action for 25 different entities. Do I need create 25 the same java-action with a different input parameter? Or is it possible to create a generic java-action where the input is a list of (any) object?
No you can't pass a list of any object currently, but it sounds like a good feature, you could request it.
