Sorry about the regression. Some components has been renamed has you can see in this post.
Normally all those components has been automatically migrated except Table::TableFooter that has been forgotten. I’m doing a patch to fix this but if you want to fix your smart view just rename your Table::TableFooter to DataDisplay::Table::TableFooter.
Hey @vince, thanks for helping. I guess the issue is on our end now. We´re using a handlesbar template with a custom js file. We´re using a component on the .hbs file as below, so I think we should update it to data-display/table/table-footer. What do you think?
