http://gwt-code-reviews.appspot.com/760803/diff/1/2#newcode139 user/src/com/google/gwt/requestfactory/client/impl/AbstractRequest.java:139: if (schemaAndId == '__gwt_ObjectId') continue; Instead you should add at the top of the loop: if (!related.hasOwnProperty(recordKey)) continue; We patch in a check for __gwt_ObjectId on Chrome in DevMode, and it is recommended practice to do this anyway for any JS value used as a map to avoid picking up spurious keys. See our Dictionary.addKeys for an example. http://gwt-code-reviews.appspot.com/760803/show -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
