      This is not an error.

      Breeze ‘complex objects’ have a ‘complexAspect’ property that is analogous to the ‘entityAspect’ that is found on ‘entities’.

      All complex objects ALSO have a GetEntityAspect() method. The GetEntityAspect method returns the top level EntityAspect associated with the complexObject ( complex objects can be nested so this may go thru multiple parent objects before returning the final parent EntityAspect – this is why this is a method and not a property).

      Entity objects by comparision have only a single entityAspect property.

    • OData Version 4.0 Support

      Support for OData version 4.0, when it is finalized. This will allow filtering by derived complex types, among other things.

      http://www.odata.org/documentation/odata-version-4-0/

      The above mentioned feature I'd like to see available with breeze:

      • Title of the page doesn't update in docs

        On Linux Mint 16, Chrome v.31.0.1650.63

        Jumping around different doc pages like MetadataStore to EntityManager to ... doesn't change what I see in the Chrome tab title area.

        • More node.js / mongodb love

          I fall in love with Breeze, but the support in node / mongodb still needs a lot of work. I can't live with breeze anymore but I can't support .NET.

          I saw the TODO but wasn't updated since August 2013.

          Things like associations would change it completely.

          I vote for some sweet love for those who don't use .NET

          • TypeScript breeze.d.ts: ValidatorFunction should return boolean

            The current breeze.d.ts file says:

            interface ValidatorFunction {
            (value: any, context: ValidatorFunctionContext): void;
            }

            Since a value can be either valid or invalid (true or false) in my opinion this should be a function returning a boolean. Also, the context parameter in the Validator constructor can be empty so it would be better if "context" is an optional parameter.
            And: the "message" part of the ValidatorFunctionContext is declared as "string" but can be a function also and "any" would be correct.

              • Add method "SaveChanges" on EntityAspect

                It would be nice if there is a method "SaveChanges" directly on the EntityAspect, similar to "RejectChanges". This makes it easier to save this and only this entity without affecting other entities that might have been changed. I know that there is a parameter on the EntityManager.SaveChanges(...) method, but having it directly on the EntityAspect makes it a little more convenient.

                    • breeze.js createError function can't handle datajs errors

                      My ODataController Post method was updating its entity's CreatedOn property with DateTime.Now value before it's saving to database.

                      Apparently datajs doesn't like DateTime.Now value and gives an error with "Invalid date/time value".

                      File: datajs-1.1.2.js - Line 2133

                      After datajs throws the exception, it falls to breeze.js createError function. However, since it's expecting error.response property, it fails to continue by giving "response is undefined" message.

                      File: breeze.debug.js - Line: 15302

                      I've updated the function by adding a check for response property;

                      function createError(error, url) {
                      // OData errors can have the message buried very deeply - and nonobviously
                      // this code…

                        • BreezeJS and Moongose

                          Hi All,

                          I am new to MEAN stack, I am to easily for Moongose based apps and developed rapid prototypes in less than 30 mins, but with Zaa example even though I can run the sample in 10 mins. The concept of metadata generation with respect to MEAN stack very confusing, where as for .NET MVC example I can easily understand.

                          • Flag which navigation properties have been loaded

                            It's currently not possible to determine if a navigation property has been loaded.

                            For example a order.orderLines. There is no way of knowing whether orderLines is empty because the order has no lines or that the navigation property has been loaded.

                            This is a real pain when you have business logic that require the object graph to be loaded. This leads you to implement boiler plate data access related code to manually track which navigation property has been loaded - something that the breeze framework should be doing.

                            This feature has been asked for on SO here: http://stackoverflow.com/questions/17798514/any-way-to-tell-if-a-breeze-navigation-property-has-already-been-loaded

                            • Breeze + Knockout validation -> new features

                              If App uses breeze and ko validation, I suggest to

                              add knockout validation rules for every fetched entity as showed in code example (here coffee code implementation for dataPropeties):

                              addRules = (breezeEntity) ->
                              return if breezeEntity.koValidationRulesAdded
                              entityType = breezeEntity.entityType
                              for property in entityType.dataProperties
                              continue unless property.validators.length > 0
                              do (property) ->
                              displayName = property.displayName or property.custom?.displayName or property.name
                              breezeEntity[property.name].extend
                              validation:
                              validator: (value) ->
                              if breezeEntity.entityAspect.validateProperty property.name, {displayName: displayName, entity: breezeEntity}
                              @message = ""
                              return true
                              else
                              @message = breezeEntity.entityAspect.getValidationErrors(property.name)[0].errorMessage
                              return false
                              message: ""
                              return
                              breezeEntity.koValidationRulesAdded = true
                              return

                              this code allows:
                              1) to validate single property with usage of all…

                              • Tools for meta data creation for breeze not depending on a server-side ORM and tools for ORM-less server-code generation

                                For me ia server-side ORM for a web application is a wrong cut. I think business logic should go as close to the data as possible to guarantee consistency, protection, and security. This means to me using stored procedures and database functions wherever possible (in a relational environment) and reasonable. In addition, if done right it's arguably unbeatably fast. The role of the Web API should be to provide access to the data across the network but not processing it.

                                Let's suppose we have to query the database for all open orders for a certain customer including order items and…

                                • Support for NotMapped properties server side

                                  it would be useful to have support for server-side properties notmapped together with the properties of normal db. Obviously readonly
                                  Thanks

                                  • Specify the version of Express to install in the Zza Example

                                    Express v4 differs a bit and will not work with the Zza Example. One recommendation would be to change the instructions until the express code is updated to: npm install express@3.5.1

                                    Once the code is updated to support Express v4, remove that specific version from the instructions.

                                        • Better documentation to create own support for any external datasource

                                          What needs to be considered on client/server side etc.
                                          Maybe with a sample?
