Microsoft.SharePoint.Taxonomy.TaxonomyFieldValue is not marked as serializable.

Question

Hi,

I am getting an error on my SP2010 production server, which is using a custom event receiver that is used to update the filename field. I am not getting this error on my staging server which is identical(as far as I know).

The code will not execute if a managed metadata field value is selected. Does anyone know how I can fix this?

 

Here is the error:

"Error loading and running event receiver ActiveStudy_UpdateFilename.EventReceiver1.EventReceiver1 in ActiveStudy_UpdateFilename, Version=1.0.0.0, Culture=neutral, PublicKeyToken=16341f78859bcca8. Additional information is below.

 

Type 'Microsoft.SharePoint.Taxonomy.TaxonomyFieldValue' in Assembly 'Microsoft.SharePoint.Taxonomy, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' is not marked as serializable."

Answer 3

Hi Dinesh,

You are correct about this. I found that only uploading the .wsp file through the Site Collection would not work correctly for the managed metadata field. When I deployed the solution as a farm solution with powershell, the code then processed correctly.

Thanks for your response.

Peter.
