I have a new namespace for my Structure Group metadata schema and I want to update all my Structure Groups using this metadata schema to the use the new namespace. I am using Elena's script here.

However, I have an error when trying to save a Structure Group. I want to use client.Update(data, ReadOptions) where data is the Metadata XML of the StructureGroup. However, it fails even when I try not updating anything, and just getting and savign the same content to the item. Here is my code and below my error. I have no idea how to get the extra info the core service wants in the xml so I can simply replace the namespace on the Structure Group metadata.

This also occurs with a Page as well.

XSD:

  • Can you add what data.Metadata currently contains to the question? – David Forster Apr 9 '14 at 17:09
  • Are you able to update the metadata using Tridion Explorer? also what kind of fields are Header and Title? – Saurabh Gangwar Apr 9 '14 at 17:39
  • It might be the case that in your schema, text field was changed from text to link, or something like this. Could you please post XSD of your schema? – Andrey Marchuk Apr 10 '14 at 6:31
  • It is possible the field type was changed. Another developer worked on it and has been making the changes to the schemas, and content porting them(!). I tested data.Metadata with empty fields and also some filled out. Same results. I am able to update through CME. – robrtc Apr 10 '14 at 8:31
  • Sorry, it is not possible to save with the GUI. Hmmm – robrtc Apr 10 '14 at 8:41

The code was OK. However, a linked Multimedia Schema had an incorrect namespace and this was the root cause of the error.
