In OData, when used in JSON Syntax, member access in "any"/"all" predicates is not allowed to use "." (dot). Instead "/" should be used - otherwise the following exception will be raised:

Microsoft.Data.OData.ODataException ist aufgetreten.
HResult=-2146233079
Message=The child type 'ToOrderKind.Name' in a cast was not an entity type. Casts can only be performed on entity types.
Source=Microsoft.Data.OData
StackTrace:
bei Microsoft.Data.OData.Query.DottedIdentifierBinder.BindDottedIdentifier(DottedIdentifierToken dottedIdentifierToken, BindingState state)
InnerException:

Breeze-Queries with POST-Method (which use JSON-Syntax) should replace "." with "/" in all "Any" and "All"-Predicates automatically. At the moment we have to do this manually.
