I have a custom widget that I've developed that (in part) utilizes the Messages component from jimu-ui. The widget works 100% if I comment out the use of the Messages component. If I comment out everything else in the widget except the Messages component it will fail. So I've been able to isolate the problem to the use of this item.
I'm importing with
import {Message, Tabs, Tab} from 'jimu-ui'
and then displaying a simple string as content.
<Message
open={messageOpen}
onClose={handleMessageClose}
// severity={messageType}
message={messageContent}
autoHideDuration={3000}
/>
messageOpen is a state variable that accepts a boolean value that is initialized as false. The callback to handleMessageClose is just a standard flipping of that state.
const [messageOpen, setMessageOpen] = React.useState<boolean>(false)
const handleMessageClose = () => {
setMessageOpen(false)
}Our enterprise environment is at 11.5 and we have installed the web apps patch. I'm using arcgis-experience-builder-1.18
