So how does having an archive help that?
i will give you an example sync: two devices: A and B user adds this vcards to device A: NAME:blubb A-ONLY-FIELD:test and syncs with B. Now the archive will contain both fields (the converter has to map the A-ONLY-FIELD of course). the vcard in device B will look like this (since B discards the A-ONLY-FIELD): NAME:blubb now the user modifies the contact on device B to: NAME:blubb-new and syncs again. Now the syncengine sees the information from B but does a MERGE! with the archive before sending it to A. Therefore A will receive this vcard: NAME:blubb-new A-ONLY-FIELD:test and no information is lost. ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
