Hello Lafama,
I guess you are using the persistent classes directly in your service contracts, which may cause various issues. The recommended way of using OpenAccess with WCF services is not to use the persistent classes as data contracts but to define additional proxy objects that wrap the information from the persistent classes and use them for data transmission. This way you can use per-call contexts (or IObjectScopes) and also avoid some other problems with the serialization of persistent objects like circular references. We even provide a code generation template that can generate those proxy classes automatically based on a domain model (.rlinq file). The template can be downloaded from
here and a sample application that demonstrates how to use it with plain WCF services is available in
our new SDK. Currently we do not have an example with WCF Workflow services. Unfortunately if you are using the "classic" OpenAccess with the Forward/Reverse mapping wizards, you will have to write the transporter classes manually.
I believe this approach will help you overcome the problems you are currently experiencing as it isolates the OpenAccess-specific code in a layer below the transport objects.
If you do not want to use this method or face troubles implementing it, feel free to send us your application and we will have a look into it. I have changed the thread type to one that allows attachments.
Kind regards,
Alexander
