We made some changes to accommodate some issues with Google Docs with our CloudDav protocol Adaptor:
1. The first change relates to creating documents directly in Google Docs and then trying to open the files directly in Pages iWork (for example). Previously this failed as the file had a zero size, as the size is unknown until Google exports it. We fixed this. Now such files created directly in Google Docs will open correctly.
2. The second change related to saving files directly back to Google Docs when creating them in Pages (or other Keynote, Numbers). These would fail because pages tried to place a zero size file lock to test write access. Other Clouds allow this but Google Docs does not, and therefore Pages would report that the file could not be saved. This is also now resolved.
