Per Hemmingson

Vote:

After upgrading a legacy webforms project from episerver 6 r2 to episerver cms 7 and then 7.5 (patch 20) I get nullreference exception when trying to load edit mode. E.g. the edit mode loads, but the Page tree doee not, and forms editing is not working either.

Any clues /help is appreciated!

Console / network gives 2 xhr error request to:

GET http://localhost:60893/secureUI/shell/Stores/metadata/EPiServer.Core.Conte…=%7B%22contentLink%22%3A%22333_17083%22%7D&dojo.preventCache=1403531001199 500 (Internal Server Error) dojo.js:15
XHR finished loading: GET "http://localhost:60893/secureUI /shell/Stores/metadata/EPiServer.Core.Conte…=%7B%22contentLink%22%3A%22333_17083%22%7D&dojo.preventCache=1403531001199".

Open up the URL request gives:

Hey,

Not quite correctly. I took a vanilla episerver cms 7.5 web.config and used it, added the parts that I knew I needed step by step.

The root cause is still unknown.

I fixed this by cleaning up my own web.config. As soon as I removed the episerver.dataStore configsection, everything works. The config that was removed was the following

<episerver.dataStore>
    <dataStore defaultProvider="EPiServerSQLServerDataStoreProvider" autoResolveTypes="false">
      <providers>
        <clear />
        <add name="EPiServerSQLServerDataStoreProvider" description="SQL Server implementation of Data Store" type="EPiServer.Data.Dynamic.Providers.SqlServerDataStoreProvider, EPiServer.Data" />
      </providers>
      <cache defaultProvider="httpCacheProvider">
        <providers>
          <clear />
          <add name="httpCacheProvider" description="Http Cache implementation for DataStore" type="EPiServer.Data.Cache.HttpRuntimeCacheProvider,EPiServer.Data.Cache" />
          <add name="nullCacheProvider" description="Null Cache implementation for DataStore" type="EPiServer.Data.Cache.NullCacheProvider,EPiServer.Data" />
        </providers>
      </cache>
    </dataStore>
  </episerver.dataStore>

as well as the declaring configsection in the top of web.config.

As we are not using dynamic data store in our EPiServer site, removing this has no side effects.

Thanks for your tip, Per.
