Steps to reproduce or a small repository showing the problem:

using the .save() method (sometimes?) produces the error TypeError: Right hand side of instanceof is not an object which is triggered by OrmUtils.compare2Objects. Since 50a0641 this uses the node-import url which is not available on browser targets. I guess this needs to be removed or polyfilled in browser/utils/Ormutils.
