You didn't actually ask any questions and it's difficult to say from this alone what's going on in your project. Could possibly be caused by an extension that doesn't do quite what it's supposed to do, or some other TextField-related client-side changes in your project. Are you trying to add components to a TextField and wondering why it doesn't work, or what brought this on?

Not to worry. I'll debug this a bit later. Was curious when it showed with error message in the console. Perhaps you are right, it is something to do with the widgetset of TextField.

I'll have to check.

Thanks. :)
