Hello

I have create my own custom module named StudentsModule following the steps as specified in products module. Module is installed but when i try to create record from the backend of the module. I get the following exception:

System.NullReferenceException: Object reference not set to an instance of an object.

at OpenAccessRuntime.Relational.metadata.RelationalTable.createPkEqualsParamExp(SelectExp se)
at OpenAccessRuntime.Relational.RelationalStorageManager.getGetStateFetchSpec(FetchPlanIF fPlan, Boolean includeSubclasses, OID oid)
at OpenAccessRuntime.Relational.RelationalStorageManager.getStateImp(RelationalOID oid, FetchPlanIF fPlan, Boolean forUpdate, StateContainer container, RelationalClass relationalClass)
at OpenAccessRuntime.Relational.RelationalStorageManager.getState(OID oid, FetchPlanIF fPlan, StateContainer container)
at OpenAccessRuntime.Relational.RelationalStorageManager.fetch(ApplicationContext context, OID oid, State current, FetchPlanIF fPlan, FieldMetaData triggerField)

I have sdk of SF version 5.2 so i have set the open access target path as

<OpenAccessPath>C:\Program Files\Telerik\Sitefinity 5.2\SDK\Content\Common\Dependencies</OpenAccessPath>

but the sitefinity application is built in sitefinity version 5.1. Is the error coming because of this version difference?

Hello,

The stack trace of the error indicates a problem in metadata which is an inication that the module is not enhanced

at OpenAccessRuntime.Relational.metadata.RelationalTable.createPkEqualsParamExp(SelectExp se)

In the .csproj file of the module make sure you have the end of the .cspro file like this:

<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />

<ProjectExtensions>

<VisualStudio>

<UserProperties OpenAccess_ConfigFile="App.config" OpenAccess_ConnectionId="DatabaseConnection1" OpenAccess_Enhancing="True" OpenAccess_UpdateDatabase="False" OpenAccess_EnhancementOutputLevel="1" />

</VisualStudio>

</ProjectExtensions>

<PropertyGroup>

<PostBuildEvent>

</PostBuildEvent>

<PreBuildEvent>

</PreBuildEvent>

</PropertyGroup>

<PropertyGroup>

<OpenAccessPath>C:\Program Files\Telerik\Sitefinity 5.2\SDK\Content\Common\Dependencies</OpenAccessPath>

</PropertyGroup>

<Import Condition="Exists('$(OpenAccessPath)\OpenAccess.targets')" Project="$(OpenAccessPath)\OpenAccess.targets" />

</Project>

All the best,
