[futuros]

Hi gurus,

please, If you have solution for my problem bellow, explain me that, I tryed allmost everything.

I work on ASP.NET application witch use EA.Repository as interface. But some time (!!!) when I try open EAP file using ASP.NET application

1.  this.myRepository = new EA.RepositoryClass();
2.  this.myRepository.OpenFile(System.Convert.ToString(Session["EAfile"]));

it fails on 2 and server returned

QueryInterface for interface EA.IDualRepository failed

Exception Details: System.InvalidCastException: QueryInterface for interface EA.IDualRepository failed.

what is wrong ? Some time this works, some time doesn't.
