Trying to disable a few columns from a catalog entry, but I'm only getting an error saying Cannot alter or drop column 'ColumnName' because it is enabled for Full-Text Search.
This Exception should be picked up, and if it's there, you should drop the Full text index (like below), and then drop the column. If I'm really after deleting the column, I don't care wheather it's indexed in any way or not.
ALTER FULLTEXT INDEX ON CatalogEntryEx_MyClass DISABLE
ALTER FULLTEXT INDEX ON CatalogEntryEx_MyClass DROP (MyColumn)
ALTER FULLTEXT INDEX ON CatalogEntryEx_MyClass_Localization DISABLE
ALTER FULLTEXT INDEX ON CatalogEntryEx_MyClass_Localization DROP (MyColumn)
