LS4: LightSpeedEntityModelBinder

Hi,

I am using MVC3 and I registered my model via LightSpeedEntityModelBinder.Register(typeof(EntitiesUnitOfWork).Assembly).

During the post back of a form I got this exception:
bei Mindscape.LightSpeed.Mvc.Helpers.LightSpeedEntityModelBinder.BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
   bei System.Web.Mvc.ControllerActionInvoker.GetParameterValue(ControllerContext controllerContext, ParameterDescriptor parameterDescriptor)
   bei System.Web.Mvc.ControllerActionInvoker.GetParameterValues(ControllerContext controllerContext, ActionDescriptor actionDescriptor)
   bei System.Web.Mvc.ControllerActionInvoker.InvokeAction(ControllerContext controllerContext, String actionName).

When I remove the LightSpeedEntityModelBinder.Register(..) call, everything is fine and the excpected valdiation error (a missing association to a required Entity) is displayed.

Reading your documentation, I understand that the LightSpeedMvcValidatorProvider transform the LightSpeed valdiation attributes the DataAnnotation equivalent. But what is the "improved experience" mentioned at the documentation for the LightSpeedEntityModelBinder?

Hi Sörnt,

The advantage of using the custom model binder is that it handles any validation errors correctly rather than the DefaultModelBinders approach of just sucking out the entire contents of the Errors property as a single string. The alternative is subclassing the DefaultModelBinder which is also mentioned later on in the same section of the guide (Model Binding for LightSpeed Entities).

In relation to the exception you are seeing, is there a repro you could provide for this? We would be keen to look at getting that fixed up of course :)

Thanks,

Jeremy

Hi Jeremy,

here is the repro.

The Bootstrapper.initializeMvcInfrastructure() registers the LightSpeedEntityModelBinder.
The HomeController displays a new Project-Entity. When submitting the form the error will be displayed.

Hi Sörnt,

The issue isnt actually occuring for me here following through those steps, instead I am just seeing the validation message indicate I need to fill out a name and if I fill out the name it completes fine. We have been shuffling things around recently (for example I notice the binder was in its old namespace) so would you be able to grab the next nightly build and let us know if solves the problem you are seeing?

Thanks!

Jeremy

The latest version fixes the error. Thanks
