NullReferenceException after installing 5.2.2

   Hi,

I upgraded from 5.1.0 to 5.2.2.
My codes are updated based on "breaking changes" documented in the release notes, and successful built.

My N-tier applications have been working before so I did not change any app.configs settings. Note that I have own implementations of ILoginManager and IEntityServerSaving in probeAssemblyNames. Examples below.

ServerConsole.exe.config:
<configuration>
  <configSections>
    <section name="ideablade.configuration" type="IdeaBlade.Core.Configuration.IdeaBladeSection, IdeaBlade.Core, Version=5.1.0.0, Culture=neutral, PublicKeyToken=287b5094865421c0" />
    <section name="EmailConfig" type="DomainModel.EmailConfig, DomainModel" /> 
  </configSections>
  <ideablade.configuration version="5.00" updateFromDomainModelConfig="Ask" loginManagerRequired="true">
    <probeAssemblyNames>
      <probeAssemblyName name="LoginManager" />
      <probeAssemblyName name="EntityServerHandlers" />
    </probeAssemblyNames>
    <!--    -->
    <logging logFile="DebugLog.xml" />
    <objectServer isDistributed="true" remoteBaseURL="http://localhost" serverPort="9009" serviceName="EntityService" />
    <edmKeys>
...
...

WinFormClient.exe.config:
<configuration>
  <configSections>
    <section name="ideablade.configuration" type="IdeaBlade.Core.Configuration.IdeaBladeSection, IdeaBlade.Core, Version=5.1.0.0, Culture=neutral, PublicKeyToken=287b5094865421c0" />
    
    <section name="SkillConConfig" type="DomainModel.SkillConConfig, DomainModel" />
  </configSections>
  <ideablade.configuration version="5.00" updateFromDomainModelConfig="Ask">
    <logging logFile="DebugLog.xml" />
    <objectServer isDistributed="true" remoteBaseURL="http://localhost" serverPort="9009" serviceName="EntityService" />
    <edmKeys>
...
...

There was no errors querying entities. But on saving entity, I have a null reference exception somewhere but was unable to trace. Server-side DebugLog.xml shows the following:

2009-09-16 18:09:44 sysuser IdeaBlade.EntityModel.Server EntityServer::GetInstanceImplementing Probed for 'IdeaBlade.EntityModel.Server.IEntityServerSaving' and found: EntityServerHandlers.DefaultEntityServerSavingHandler

Is there anything I need to re-set in my app.config, like the "Version=5.x.x.x"? Have I missed anything?
Thanks much!
