Mark BusinessBase object IsNew=false

[CROprogrammer]

Is there any way to mark BusinessBase object's IsNew property to false?

MarkOld?

I have the next method in my MVC controller:

    [HttpPost]
    [ValidateAntiForgeryToken]
    public async Task<IActionResult> Edit(Project project)
    {
      project.MarkAsOld();

      if (await SaveObjectAsync(project, true))
      {
        return RedirectToAction(nameof(Index));
      }

      return View(project);
    }

and in my async business rule I check that Project's code is unique, and when I'm editing project I disable project code editing. So the way I determine if I should check if project code already exists is so that I check if object is new or not. If the object is new, then I do not check my async rule.
But somehow my async rule is being called, when I submit my form, beforeEdit method where I mark project as old. Why is that? How can I avoid that business rules are being checked before I call Save method in my MVC Controller's method?

The rule is probably being executed when the postback data is bound to the properties as the Project object is being created so it can be passed into the Edit method - so before any of the code in the Edit method is executed.

This occurs in Csla.Web.Mvc.Shared.CslaModelBinder:

csla/Source/Csla.Web.Mvc.Shared/CslaModelBinder.cs

Line 59 in 91921c0

private void BindBusinessBase(ModelBindingContext bindingContext, object result)

I don't see a way to prevent this behavior without altering CslaModelBinder - probably to globally disable the automatic running of rules, which would require that your code in the controller call CheckRules when and if you want the rules to run.
