StructureMap exception: no default value for the PluginFamily module

Question

I have a SysMsgManager class defined in a CoreService project as follows:

public class SysMsgManager 
{
    private ISysMsgRepository _SysMsgRepository;

    public SysMsgManager()
    {
        _SysMsgRepository = ObjectFactory.GetInstance<ISysMsgRepository>();
    }

    ....
}

In my DataAccess project, I have the ISysMsgRepository interface and two specific implementations defined as follows:

namespace DataAccess.Repository
{
   [Pluggable("Default")]
   public class SysMsgRepository : ISysMsgRepository
   {
      ...
   }
}

namespace DataAccess.Repository
{
    [Pluggable("Stub")]
    public class SysMsgRepository_Test : ISysMsgRepository
    {
        ...
    }
}

and this is what I have in the StructureMap.config file.

<StructureMap>

<Assembly Name="CoreService" /> 
<Assembly Name="DataAccess" />

<PluginFamily
    Assembly="DataAccess"
    Type="DataAccess.Repository.ISysMsgRepository"
    DefaultKey="Default" />

</StructureMap>

When I try to run my application, I received the following error:

StructureMap exception code: 202 \ nNo The default instance defined for PluginFamily DataAccess.Repository.ISysMsgRepository, DataAccess, Version = 1.0.0.0, Culture = neutral, PublicKeyToken = null

Can someone help me solve this problem? Thank!
