[TYPO3-dev] Extbase: Setting relational field to empty using frontend´

[Anders Gissel]

Hello Stefano,

your solution looks a bit hack'y, but it also looks like it would work. 
At least the logic is easily determined, so thanks for that!  I'll try 
crossposting my question in the other newsgroup and see if I'll have 
more luck there. :-)


Best regards,
Anders
