[Solved] Error on build

[Thomas]

I am getting the following error when I do a build on the project:

Error 104 OpenAccess Error: Telerik.OpenAccess: Updating SQL schema failed. No metadata has been registered for class Database.Product.Product. (This usually indicates, that either this class is not declared persistent or it is declared persistent but not enhanced. The class was loaded from file:///C:/Projects/TCC/trunk/Database/bin/Debug/Database.dll.) TCC 


Product in AppConfig:

 

 

           <class name="Product">
            <field name="_productId" null-value="exception" />
            <field name="_isActive">
              <extension key="db-column">
                <extension key="db-sql-type" value="BIT" />
              </extension>
            </field>
            <field name="_name">
              <extension key="db-column">
                <extension key="db-column-name" value="name" />
                <extension key="db-length" value="100" />
                <extension key="db-sql-type" value="NVARCHAR" />
              </extension>
            </field>

 

 

And Event, which inherits (vertically) from Product:
          <class name="Event">
            <extension key="db-index" value="StartDate">
              <extension key="db-unique" value="false" />
              <extension key="db-clustered" value="false" />
              <extension key="field-name" value="_startDate" />
            </extension>
            <field name="_students">
              <collection>
                <extension key="db-link-table" />
              </collection>
            </field>
            <field name="_city" null-value="exception">
              <extension key="db-column">
                <extension key="db-length" value="100" />
                <extension key="db-sql-type" value="NVARCHAR" />
              </extension>
            </field>
            <field name="_endDate" null-value="exception">
              <extension key="db-column">
                <extension key="db-type" value="DATE" />
              </extension>
            </field>
            <field name="_eventType" null-value="exception" />
            <field name="_startDate" null-value="exception">
              <extension key="db-column">
                <extension key="db-type" value="DATE" />
              </extension>
            </field>
            <field name="_state" null-value="exception">
              <extension key="db-ref" value="_code">
                <extension key="db-column">
                  <extension key="db-column-name" value="state_code" />
                </extension>
              </extension>
            </field>
            <extension key="db-inheritance" value="vertical" />
          </class> 

Any ideas?
Thanks

Hi Thomas,

Is it possible that you have two "Product" classes in your project and they are in different namespaces. Maybe the "Product" class in your app.config is not registered within the correct <namespace> node.

Hi Lafama,

Is it possible that you have tried to use both the old reverse mapping and the new visual designer approaches in the same project? The two methods use different versions of the enhancer tool and if the wrong one is used, problems like this could be observed.

Best wishes,

Hello,

I had the same problem (at runtime), and I was using a project where I had a model previusly.
I removed the project and created a new one. Everything worked ok.
