We found that List view Swipe is not compatible with Mendix 8.0.
We are looking into this issue at the moment.
I will keep you posted
[UPDATE]: We released version 1.2.0 and is now available in the app store. Please note that you might need to add a class `widget-listview-swipe-foreground` to the foreground container to make it work
I have been following the training doc of “becoming a rapid developer” and tried the List view Swipe widget twice.(https://academy.mendix.com/link/module/107/lecture/889/10.3.4-Configure-the-Swipe-Elements)
No luck to make it work. I am using the latest Mendix Studio Pro 9.02.
