Any way to recover model passed to POST action when inside OnException(ExceptionContext filterContext)?

Situation is this:

I can\'t find a way of getting the viewModel that was passed to the POST action method.

You could create a custom model binder that inherits from DefaultModelBinder and assign the model to TempData:

public class MyCustomerBinder : DefaultModelBinder
{
    protected override void OnModelUpdated(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        base.OnModelUpdated(controllerContext, bindingContext);

        controllerContext.Controller.TempData["model"] = bindingContext.Model;
    }
}

and register it in Global.asax:

ModelBinders.Binders.DefaultBinder = new MyCustomerBinder();

then access it:

protected override void OnException(ExceptionContext filterContext)
{
    var model = filterContext.Controller.TempData["model"];

    ...
}
