Integration errors
Modern integrations (the Sync class)
If a "modern" integration fails to transfer an object, an error will appear on the object, and also in this list. So this is an easy overview of all integration errors. It is possible to press the red light icon, to try the transfer again.
Old integrations (the Integration class)
When the Integration→doExport() function returns an error, this should be reported using Module::reportErrors().
