DFS: DfsBaseException and Emc.Documentum.FS.Runtime.SerializableException

I am using DFS (.Net Productivity layer) on Documentum Developer Edition 6.6. In the DFS-SDK I see description of an exception class DfsBaseException. But in fact, if an error happens, I meet exceptions System.ServiceModel.FaultException<Emc.Documentum.FS.Runtime.SerializableException>.

Can someone explain – what is in fact the exception model in the DFS? And can I somehow get some error code that could help me to recognize: what is the error? I need to detect situations like ‘the Checkout operation has failed because of the object is already Checked Out’ etc?

Did you get any reply to this or did you find a solution? We're struggling with the same issue

DFS .NET PL follows the WCF style exception handling. Please refer to section "Handling SOAP faults in the .NET productivity layer" of DFS development guide.

Quoted words:

The DFS .NET productivity layer wherever possible avoids manipulation of serialized SOAPfault data. Specifically, it does not translate a FaultException representing a SOAP fault into aServiceException. Instead, serialized exception details in the service response are wrapped ina FaultException<T> and thrown on the client. T in this case is a type representing SOAP faultdata that implements System.Xml.Serialization.IXmlSerializable, such as ServiceException. Theseservice exceptions representing DFS SOAP faults are not native C# exceptions and do not extendthe Exception class. Therefore they are not themselves thrown, but are instead are thrown asFaultException<ServiceException>, FaultException<CoreServiceException>, and so on.

Thanks for the information but all I'm getting is a Emc.Documentum.FS.Runtime.ServiceInvocationException, not a FaultException<T>. From that ServiceInvocationException I cannot get the details I need. The innerexception of a ServiceInvocationException is a regular FaultException by the way, not a generic one.
