[TYPO3-english] External Import extension: importing XML - records are not update with disabledOperations => ' '

[Bert Hiddink [BENDOO e-work solutions]]

Hello,

I'm testing this extension for a specific project. Following the great 
tutorial, when testing with a RSS-feed (news from TYPO3.org), news items 
are re-inserted instead of updated.

I have set:
   disabledOperations => ' '
in the TCA for the news-plugin.

A bug? Did I miss something?

Thanks so far!

Regards,
Bert
