#4 more yosemite hiccups

[r polson]

Hi-
Yosemite error and couldn't create reference temporary file.
small edit to include "as text" to set tempfile line:
-- export the references list to a temporary file
tell application "BibDesk"
set tempfile to (tempDir as text) & "export_" & templateFileName
export theBibDoc using template (file templatePath) to (file tempfile) for pubList
end tell
