Force to update object property

Hi,

ObjectManager tracks property changes but in my use case I would need to update my "ObjectState"-property in any case. Server side core-application might have changed that property and client needs to force it's own state. Now flush updates only changed properties.

I have tried evict + saveOrUpdate, but it seems to broke referenced proxy objects. 

Is there a way to tell ObjectManager that property have been changed or some other recommended way to handle updates?
