My EPiServer version: 5.2.375.236
In the following thread Hieu Doan is mentioning a bug about copying properties of type "LinkCollection": http://world.episerver.com/Templates/Forum/Pages/Thread.aspx?id=37266&epslanguage=en
I am experiencing problem with this. When I copy a page with a LinkCollection and have set a specific language for a link in the collection I get the error mentioned when I try to copy that page.
Is there a bugfix for this or when will it come?
Please contact EPiServer Support for this fix.
