Messagebox not enabled

[martinschm]

Hi,

i have this error message in my logs
message handler implemented, but messagebox not enabled. Define common.messagebox in io-package.json for adapter or delete message handler.

Not sure what it means, I thought I report it anyway.

the message handler was a comment, may be there is a check within the js-controller. I have deleted the commented lines
