The arguments to the BeforeSetAnyProperty property interceptor need to be less specific.  Since the interceptor will be called before setting any property on the entity, the arguments need to be suitable for any property type.  There are a number of different arguments which will work, a few would be:
 
  BeforeSetAnyProperty(IPropertyInterceptorArgs args)
 
  BeforeSetAnyProperty(PropertyInterceptorArgs<Engine, object> args)
 
Check out the BeforeSetAttribute in the DevForce Help Reference installed with the product for more possibilities.

Good Evening,
 
I'm trying to edit an entity that I've created and am getting a "Cannot Coerce...." error.
 
Specifically,I have an object (say, a car) that contains an object (Engine). I'm loading this from the database without any errors. But, I want to 'click a button and select a new engine from a child window and put this selected engine into the engine property of the car (and essentially removing the original engine).  My code looks like this:
 

if (box.DialogResult == true){

_model.CurrentCar.EngineId = box.SelectedEngine.EngineID;

_model.CurrentCar.Engine = box.SelectedEngine; }

To confirm - the Engine and Selected Engine are the same IdeaBlade entity object type (just different instantiations).
 
The Error message is: "Unable to construct a PropertyInterceptorAction for method: BeforeSetAnyProperty' in type 'Namespace.Engine' Cannot coerce IdeaBlade.EntityeModel.NavigationEntityPropertySetInterceptorsArgs..."
 
 
Any suggestions where to look for an answer?
