Problems when importing node translations

Hi,

when importing nodes with multiple translations some fields do not get imported correctly for translations other than the original one.

The problems I have seen:

• the uid is not imported correctly, it looks like it's set to the drupal user executing the import command (Anonymous by default);
• some fields like promote and sticky do not get imported correctly;
• the created and changed times are set to the time of the import, not to the time in the json file.

As said this is only for the "translations", the entity in the original language seems to be imported just fine.

To replicate this:

1. create a site with two languages (e.g. English and Italian);
2. create a node in the default language (setting sticky and promote);
3. add a translation (look at the created and changed time);
4. export the node (possibly as user 1, not to loose informations);
5. delete the content from the site;
6. import the content;
7. verify what I wrote above

I am attaching some test content which you can import on a site which have English and Italian languages.
Can you confirm the issue?

Maybe it's a core problem?

Thanks,
Antonio
