Model and Boolean throws error



I’ve got a strange problem where I can’t us ‘boolean’ as a type for fields (model) because of the error message that I receive. And if i don’t add “NULL” as the second field for addField the callback throws an error.

If I make the field a regular input field instead of a checkbox it works without error.

Please, “HELP”! :wink:

Hi, can you show the code where you define the field data type and the addField code?
