Error 'getClassMetaData() on unresolved oid'

[devoas]

Hello,

We are getting following error.
 
Error 'getClassMetaData() on unresolved oid'  when transaction.flush is executed in order to get id and update in another table before final commit.
While searching for this error on google found some code from  "Versant Open Access - JAVA" 

Can you please advise what can be the reason of this error. 

Thanks,
devoas.

Dear Jan,

I have following code

try 
{
scope.Transaction.Flush();
}

catch (exception e)

{

}

Exception catch and string send to you.... Also I checked e.innerException which is null...  Following is for your reference.

{"Called 'getClassMetaData()' on unresolved oid"}
    [Telerik.OpenAccess.OpenAccessException]: {"Called 'getClassMetaData()' on unresolved oid"}
    Data: {System.Collections.ListDictionaryInternal}
    HelpLink: null
    InnerException: null
    Message: "Called 'getClassMetaData()' on unresolved oid"

Hello devoas,
I looked through our code and i cannot see where this can happen, weird. Can I get more information what you are trying to flush, maybe you have an example for me that shows the problem?
