Multifield Issue AEM6.3

Hi all,

I've been looking in the community to find the solution but I couldn't, every problem that I saw in threads had the same answer: look into helpx documents, but they're not the solution they are just tutorials and I followed them, still not working. It working on html but when I wanted to edit the values dialog opens in empty shape. I'm sharing my dialog's content.xml. Should I implement an editconfig dialog?

Best regards,

Ogün Adsay.
