Can't download DOC or PDF from iCloud web app Possible Duplicate:
  Why won’t iCloud let me download Pages documents uploaded from a computer?  




I recently updated Pages, Numbers and Keynote to the latest versions, and my OS to Mountan Lion. I went ahead and tried the "documents in the cloud" feature by saving a Pages document on iCloud. 

As a long time user of the now shut-down iWork.com beta, I was surprised and pleased to find the following menu on the iCloud.com iWork web app:



iCloud appears to allow download in other formats but the options are disabled for some reason.
How can I enable this document to be downloaded in PDF and WORD formats?
It seems to be enabled after having opened on iOS, my thinking is that it's something to do with the message you get when opening an iOS version of something created on OS X, which lets you open copy or open, saying that it may look different. Anyway, after opening on iOS, you can download from iCloud.com in all three formats, however, after saving or editing on OS X the PDF and DOC options are blanked again.
