Remove category from every node version

Roberto Di Gisi

Hi,
we have a category that has been assigned to about 100'000 documents but has never been used. We have decided to remove this category from all documents and from all their versions in order to delete the category itself.

Is it clear that before delete the category, I have to remove it from all documents. To accomplish this I've written a quick and ugly java function (CWS).

Removing the category from a node is quite simple:

metadata = manager.getDocumentService().getNode(12345).getMetadata();for (int i=0; i<metadata.getAttributeGroups().size(); i++){  if (metadata.getAttributeGroups().get(i).getDisplayName().equals("CategoryName")){    metadata.getAttributeGroups().remove(i);  }}manager.getDocumentService().setNodeMetadata(12345, metadata);

but remove the category from one old version (in this case version 1) of a node, I get the following error message:

metadataV1 = manager.getDocumentService().getVersion(12345,1).getMetadata();for (int i=0; i<metadataV1.getAttributeGroups().size(); i++){  if (metadataV1.getAttributeGroups().get(i).getDisplayName().equals("CategoryName")){    metadataV1.getAttributeGroups().remove(i);  }}manager.getDocumentService().setNodeMetadata(12345, metadataV1);

Error updating attributes - data references an earlier version of a Category than is currently set.

Does someone have any idea?

Thanks, R.

This is probably not possible in CWS unless you write an override yourself.OT has consistently said that metadata belonging to an earlier version is treated as Record and is immutable.See several posts by Kyle Swidrowich.I believe two other interfaces would allow this(old lapi and object importer) but cannot check or confirm.Why is old category data on a version bothering you?

Well, if I called the wrongnumber, why did you answer the phone?
