I’ve done a little testing here. Bottom line is that DTTG on an iPad running iOS 7.x is not compatible with Numbers, Pages, or Keynote.
Documents opened from DTTG to Numbers, Pages, or Keynote will import correctly to those apps, but it is a one-way street. Any changes made in Numbers, Pages, or Keynote cannot successfully be sent back to DTTG. I don’t think this is new with iOS 7.x, but it should be noted and using Numbers – especially – Pages and Keynote with DTTG should be avoided. I recommend iCloud for now – it is generally safe and reliable for transferring documents, even though it is not possible to know what Apple is doing with your data. But iCloud and DEVONthink have no integration, of course
For example, for Pages and Keynote, if I make an example of each of those documents on 10.8.5 running the current version of those apps, sync them to DTTG, and open them in their iPad counterpart apps, I can edit them without a problem. However, if (without changing the document name so that the URL reference for DTTG is preserved) the Pages or Keynote document is “Opened In…” DTTG the changes do not get transferred back to DTTG. The edits are not lost – if you are using iCloud then the iCloud version is correctly updated and the changes are available back on the desktop by opening the document from iCloud in Pages or Keynote as the case might be.
In the case of Numbers: a document created on the desktop, synced to DTTG, then opened in iOS Numbers for editing, closed, and then “Opened In…” DTTG (in Numbers format). The changed document is not reconnected to the instance in DTTG. A new numbers document whose name is something like “094BDD16-C3CB-48A8-AD9A-79FF847CF43A-1.numbers” is created in the DTTG Global Inbox. This is not a real Numbers document – it is corrupt and useless. Once again, the edits are not lost – if you are using iCloud then the iCloud version is correctly updated and the changes are available back on the desktop by opening the document from iCloud in Numbers.
After updating to ios7 on my ipad, I can’t edit a rich text document (either an existing one or a new one) without the program crashing. As soon as I click into the document to type, it’s done. Really hoping the new version is released soon!! I’m tired of the work-arounds and sort of afraid to sync back to my database until a new version is released… Hurry, guys!
As you may know we are already working heavily on DEVONthink To Go 2. Here in our labs it already displays also Numbers documents.
We hope this response has sufficiently answered your questions."[/i]
Since no timescale is mentioned I have got to assume it is not in the next few days.
So I have had to stop using DEVONthink Pro Office and DTTG altogether at least for now. I have exported all my DEVONthink documents out of the databases, so that I can sync with my iPads and iPhones by another means.
I will revaluate the situation when DTTG 2 is released.
It is not as if iOS7 was released without warning. Just about every other iApp I use has been re-issued for iOS7 compatibility. I assume the DT team were part of the pre-release testing.
