ing+IBM+Notes+Traveler+9.0.1#action=openDocument&res_title=How_do_I_work
_with_my_contacts_on_my_Android_device_U901&content=pdcontent
but the edit choice in menu list are missing.
I have found a workaround.
1. Disable Contact sync in IBM Traveler App
2. Create a new Account using Exchange Active Sync versus Traveler Server and select ONLY contacts (without sync of mail, calendar, todo, etc.)
In this case syncing work fine and i'll be able to edit / insert / delete contacts.
I think isn't a problem of samsung-contacts-app but a Traveler integration issue.
