It's unclear to me which part is managing the linking. Does your calendar part subclass FW_CLinkManager, FW_CLinkSource, and FW_CLinkDestination? If not, you're relying on the linking support in the container part (ODFDraw or ODFTable). The linking code in the container part will paste the entire calendar part every time the link is updated. In other words, the 2nd calendar part is created by the container's linking code, not you. It's a "live copy" of the 1st calendar part.
My second question is, which part is handling the Paste As command? If it's the calendar part, and it doesn't provide its own linking support, then you're not actually creating a link but doing a simple paste.
