I want to put a "Delete" button and a "Cancel" button on each row of a list of Customers. The "Cancel" button is disabled when a customer is "Unchanged". But when a customer transitions to a changed state ("Added", "Modified", "Deleted"), I want to enable the "Cancel" button so the user can reverse the changes -- whatever they are -- before saving. I can almost do this by subscribing to customer.entityAspect.propertyChanged . A property change signals a potential change in the EntityState . I can subscribe to that event and have my handler update an isChanged observable that I've added to my

Our project currently uses Silverlight to consume an Odata service. This has made life pretty simple since we can just reference the OData service thus giving us generated service reference/entities. However there is some discussion on whether we should move to Html (html5). I'd like to know what to expect if we make this change. We'd be leveraging a framework like jQuery of course. My main concern is how to consume the same OData service via JavaScript/jQuery. How are we suppose to deserialize/serialize entities returned from this OData service? Is our data contract supposed to be hard-coded

I am encountering a recurring problem that just makes no sense, and hoping someone (in the Breeze team?) can shed some light. The following model illustrates the entities in question. As you can see, I'm adhering pretty strictly to Entity Framework conventions in my property names, and as a result, if I check in SQL the cascade on delete rules are set by EF code first when it creates the db. Now, when I try to delete a BusUnit manually in SQL, the delete cascades correctly and the corresponding BusUnitDimensions are also deleted, as it should be. Likewise, if I delete a Dimension in SQL, the

I am starting to use breeze.js for my ODATA service. I am using a SharePoint ODATA api and i have an example of how to use it with jQuery-Ajax. To make this work with breeze would be so f-ing awesome. Can anyone help me to translate this jQuery-Ajax call into breeze.js ? ... or push me in the right direction? $.ajax({ url: “../_api/SP.WebProxy.invoke”, type: “POST”, data: JSON.stringify({ “requestInfo”: { “__metadata”: { “type”: “SP.WebRequestInfo” }, “Url”: “http://get_my_data_from_this_url”, “Method”: “GET”, “Headers”: { “results”: [{ "__metadata": { "type": "SP.KeyValue" }, "Key": "Accept",

I'm using breeze with Code First EF. My production DbContext has IDatabaseInitializer that throws an exception if !context.Database.CompatibleWithModel(true) . If I create a context like suggested in the documentation database compatibility cannot be checked. // The following line will throw NotSupportedException. // Unable to verify the compatibility of the model because // the DbContext instance was not created using Code First patterns. var context2 = new MyDbContext(EntityConnection, false); // create a DbContext using the existing connection How should I instantiate DbContexts providing

I'm trying to save an Entity that was loaded using a classic WEBAPI ODATA service. When saveChanges is called on the client side, the modified entity is found and then the code goes into ´createChangeRequests´ and because the entityState is modified it goes into the function : function updateDeleteMergeRequest(request, aspect, prefix) { var extraMetadata = aspect.extraMetadata; var uri = extraMetadata.uri; if (__stringStartsWith(uri, prefix)) { uri = uri.substring(prefix.length); } request.requestUri = uri; if (extraMetadata.etag) { request.headers["If-Match"] = extraMetadata.etag; } } However
