"Popup to choose user" not working during migration

[heinjorge]

Although I checked the option "Popup dialog to choose users" when I do the migration process, the popup never appears.

I've downloaded the source of GAST and checked that the necessary condition that triggers the dialog is never reached. Explanations ahead...

The condition is located in the file/class "Worker.java, line 421, function: migrateMetadata()": else if (owners.size() > 1)

In the same file, line 410, we retrieve the possible owners: List<Owner> owners = getPossibleOwners(oldDbms, id, xml);

But, according to my analisis the getPossibleOwners() method returns a List having 1 owner maximum.
