Doing some mobile IFS6 u16 testing on a emulator, run into a strage issue with Mobile attachments.

1.Assign a task to a device

2.Once recieved on the device, go offline

3.Add a Task attachment on the device

4.On the smart client, complete the task

5.On the device, go back online and sync

6.Observe on the smart client that the attachment has not synced back, even though all other notes etc do.

7.Repeat with a fresh task, but DO NOT complete task on smart client

8.Observe that attachment does sync back to smart client

It seems after doing some testing, that Attachments on a device DO NOT become persistent records on the device UNTIL it has synced with the smart client.  If the Task on the smart cleint  is complete, then the attachment is simply discarded, if not completed then it does become a persistent record on the mobile device once synced.

Any clues why it behaves like this?
