I'm integrating InfoPath through the K2 Studio interface.  Everything's fine with one view, but when I add any extra views I get the following error which I have truncated:

"An item with this name already exists in the collection.  Parameter name: item

at

SourceCode.Workflow.Design.InfoPath.FormTemplate.DesignerNameCollection.Insert(Int32 index, DesignerNameObject item) at

... "

and there are 8 more locations in the same error box.

If I try to continue I get "An item with this name already exists in the collection.  Parameter name: item"

The 2nd view definitely has another name than the original had.

I've also tried making the changes external to K2 and importing that form, and I get the same error as noted three lines up.
