To simplify things and help our users to be more productive, we have archived the current forum and focus our efforts on helping developers on Stack Overflow. You can post new questions on Stack Overflow or join our Discord channel.
We are using following add-ons and we are kind of stuck because these are not (yet) available on Vaadin 7 (alpha-2 or later).
Please suggest how do we proceed? Can the author of these add-ons please find some time and upgrade them to 7?
Three of the four add-ons have their own issue tracker links on the directory pages, so you could perhaps create enhancement requests for this in the project issue trackers if none exist.
