[Flow] Ignore validation errors for related object

[Stephen Bungert]

I have a form for my main objects - books, they have a onetoone 
relationship with another object - an image, but an image isn't 
required. The problem is, that this object has two fields that are 
required, so my main object's update action reports validation errors.

I can create books with images, and images can be deleted too, but I 
can't save my book without validation errors because of the required 
fields in the image object.

Is there anyway of over-riding these errors in my book's update action?

Thanks for any help.

Stephen.
