Error at deployment

[LordRevan007]

Hello there,
I am using Telerik open access orm with postgresql to create a desktop based application that will be run in LAN area. I shared app.config through all of my projects that are in my solution changed my connection string with other one and no problem appeared. But at deloyment when I ran a query against my db I get the following exception:

An item with the same key has already been added. mscorlib    at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)
   at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
   at Telerik.OpenAccess.DBRegistry.GetDatabase(String urlOrConnectionId, Configuration& configuration)
   at Telerik.OpenAccess.Database.Get(String connectionString, BackendConfiguration backendConfiguration, MetadataContainer metadataContainer)
   at Telerik.OpenAccess.OpenAccessContextBase.GetDatabase()
   at Telerik.OpenAccess.OpenAccessContextBase.GetScope()
   at Telerik.OpenAccess.OpenAccessContextBase.ClearChanges()

Thanks in advance for any suggestion.

Hi Lordrevan007,
Can it be that you catch the exception that was thrown by the same context and do this ClearChanges() in the exception block? It looks like you are hiding the real cause.

Nevertheless I have changed the code so that this error cannot occur in the future. 

Best wishes,

Thanks a lot for the solution, I just remove clearChanges and it worked like a charm. I hope there won't be any problem.

Thanks!
