I am using Content Porter to export/import a component which links to an ECL stub component. When exporting and importing I have the Structure and Content dependencies checked (and no others). If I look in the export zip, I can see the stub component and the folders that contain it are included, however when I run the import, I get an error:
2015/02/24 13:14:59 <132> [Error] Tridion.ContentManager.ImportExport.ImportExportException: Item '/webdav/000%20Empty%20Master/Building%20Blocks/System/stubs/6B8/777/ecl%3A0-mm-185-dist-file.ecl' cannot be imported because it is absent on import TCM and its content was not exported to the package.
UPDATE: It seems to be a problem with Content Porter finding dependencies - as if I run the import twice from the same export package, the first time for the top level publication (000 Empty Master) which contains the stubs, and the second time for the other blueprint levels, it works OK.
