Here's a weird one which makes no sense to me:

I've been working on a dropdown element with two items. Everything works OK when I manually entered the Screentip and Supertip texts to be displayed.

Now I want to change these to Dynamic Attributes by using getScreentip and getSupertip. However, I get the following error for both of these: "getScreentip attribute is not declared" and then same for getSupertip.

All the similar remaining dynamic attributes in the file work OK when validated. It's just the four in the dropdown element which seem to be playing up.

Is it something to do with the fact that it is a dropdown?
