angularjs - Breezejs - why don't changes to non-scalar or complex data properties trigger change events? -

-

i'm using non-scalar , complex data properties in breeze. work fine, except entitychanged , propertychanged events aren't triggered when items added or removed non-scalar property, or when properties changed on complex property.

how can notified when non-scalar or complex properties change?

manager.metadatastore.addentitytype({     shortname: 'thing',     namespace: namespace,     dataproperties: {         id: {             datatype: breeze.datatype.guid,             ispartofkey: true         },         strings: {             datatype: breeze.datatype.string,             isscalar: false         },         object: {             datatype: new breeze.complextype({                 shortname: 'object',                 namespace: namespace,                 dataproperties: {                     a: { datatype: breeze.datatype.string },                     b: { datatype: breeze.datatype.string }                 }             })         }     } });

changes instances of scalar data properties (i.e. primitives , complextype's) raise change events on parent entity. changes nonscalar data properties raise "arraychanged" event on associated collection. see:
