Hi,

According to the documentation (http://drc.ideablade.com/devforce-2012/bin/view/Documentation/enum-types) we can have an enum defined in an external assembly. You explain we have to check an option when using an EDMX but what about CF ?

My enum is defined in assembly A. My model (assembly B) reference this assembly and use this enum in an entity.

My issue :

In he ibmmx the AssemblyQualifiedName of my enum is defined with the namespace B and not A. So it throw an exception when the model is loading because it can't find this enum in the assembly B.

What should I do to be able to use my enum in CF ?

I am using Devforce 7.0.3 and Cocktail 2.2

We haven't seen this issue in our testing.  In our testing the generated ibmmx has the correct AssemblyQualifiedName for the external enum, and works correctly at run time.
 
First delete and re-generate your ibmmx to make sure it's current.  If the problem persists, can you post a snippet of your entity and enum classes, and the full error message and stack trace?

Deleting the ibmmx fixed it.
Regenerating the project after I moved the enum to another assembly didn't update the ibmmx.

thanks

That regeneration problem would be a bug.  Thanks for reporting this.

I have an issue with a Nullable enum in a projection.


My KnowType is declared like this in my model assembly:

    [DataContract]
    public class SearchItem : IKnownType
    {
        [DataMember]
        public int Id { get; set; }

        [DataMember]
        public SexEnum? Sex { get; set; }
    }
    
SexEnum is declared in the assemblies Consts.dll and Consts.SL.dll    

When I query the model and create the projection, an exception is raised because the type Nullable<SexEnum> can't be found in Consts.SL.

It works if I change declaration in the KnownType to :

        [DataMember]
        public SexEnum Sex { get; set; }


The exception :

Caught exception: IdeaBlade.Core.IdeaBladeException: Unable to locate type: System.Nullable`1[[Consts.Enums.SexEnum, Consts.SL, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]], mscorlib, Version=5.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e. Check that the assembly holding this type is available in the bin/exe folder.

An alternate fix is to change the assembly name for the Consts.SL project to that of the .NET project.   The underlying issue has to do with a somewhat arcane type mapping problem in DevForce.

it worked, thanks.

Will you fix this issue ?

We will, but it probably won't be in the next release
