This question is sequel of BreezeSharp - ExecuteQuery fails with NullReferenceExeption
In my server side entity I have enum property:
[Required]
public DataStore DataStore { get; set; }
This property in client side entity is defined like this:
public DataStore DataStore
{
get { return GetValue<DataStore>(); }
set { SetValue(value);
}
When controller method return data to client, serialization error occur: "Input string was not in a correct format."
Here is StackTrace:

When I exclude DataStore property from model, everything is working fine. It looks like that BreezeSharp is trying to parse enum as int.
I tried defining client side property as string, but that raises InconsistentCLRPropertyDefinition metadata mismatch. I also tried defining client side property like this:
public DataStore DataStore { get { var dataStore = this.GetValue("DataStore"); return DataStore.DEV; } set { this.SetValue(value); } } But issue occurs before get is hit.
I looked at JsonEntityConverter.cs, and it looks like that enum is not handled separately at this point:
private void ParseObject(NodeContext nodeContext, EntityAspect targetAspect) {
// backingStore will be null if not allowed to overwrite the entity.
var backingStore = (targetAspect == null) ? null : targetAspect.BackingStore;
var dict = (IDictionary<String, JToken>) nodeContext.Node;
var structuralType = nodeContext.StructuralType;
// needs to be the current namingConvention
var nc = _mappingContext.EntityManager.MetadataStore.NamingConvention;
dict.ForEach(kvp => {
var key = nc.ServerPropertyNameToClient(kvp.Key, structuralType);
var prop = structuralType.GetProperty(key);
if (prop != null) {
if (prop.IsDataProperty) {
if (backingStore != null) {
var dp = (DataProperty)prop;
if (dp.IsComplexProperty) {
var newCo = (IComplexObject) kvp.Value.ToObject(dp.ClrType);
var co = (IComplexObject)backingStore[key];
var coBacking = co.ComplexAspect.BackingStore;
newCo.ComplexAspect.BackingStore.ForEach(kvp2 => {
coBacking[kvp2.Key] = kvp2.Value;
});
} else {
backingStore[key] = kvp.Value.ToObject(dp.ClrType);
}
Does anyone has idea where to proceed from here?
