Comment 21 for bug 150937

Taking a quick look at the code, it seems that SwFmtFtn::GetFtnText() in sw/source/core/txtnode/atrftn.cxx returns only one text node from the footnote. If the footnote contains multiple paragraphs, then only the first paragraph is returned. However, I did not find the way to get the number of text nodes in a given footnote. It is not stored in the object.

You can use "soft returns" (Shift+Enter) to separate lines in footnotes, that works.
