Side by Side WCF workflow service hosting with devArt oracle store fails with: ORA-19025

[aconst]

Hi,

I am using:
DevArt dotConnect for Oracle v8.1 instance store for Framework 4.5 (dll version 8.1.26.2)
Appfabric 1.1 as a host
Visual Studio 2012

Problem:
I am trying to achieve side by side WCF workflow service implementation, hosted in AppFabric. I tried with several of my workflows and I always get the same error. I even tried with one with just a WCF receive activity.
The steps to reproduce are as below (you can refer to this post as well: http://code.msdn.microsoft.com/Side-by- ... g-0fe24cd3, here it has a nice video that explains in detail all the necessary steps)
1. Create a service i.e. Service1.xamlx
2. I create a folder "Service1" under App_Code folder
3. I copy Service1.xamlx to "Service1" folder and rename to Service1_v1.xamlx
4. I change the DefinitionIdentity of my root Service1.xmlx. Use any name/version
5. I try to run the service and get below exception:
WWFSCHEMA81_45 -> name of my oracle schema of the instance store
Service1 -> name of my WCF service

Appfabric 1.1 as a host

We are working on the implementation of AppFabric Dashboard. Currently it is not supported.

1. Create a service i.e. Service1.xamlx
2. I create a folder "Service1" under App_Code folder
3. I copy Service1.xamlx to "Service1" folder and rename to Service1_v1.xamlx
4. I change the DefinitionIdentity of my root Service1.xmlx. Use any name/version
5. I try to run the service and get below exception: [...]

Please send us a small test project so that we can reproduce the ORA-19025 error in our environment.
