A closer look to some add-on pages tell that they explicit not support vaadin 7. How complex will it be to make a add-on vaadin 7 ready and what does your experience say how long after the v7 release it needs that most common add-ons are ready for the new version?
yep this is definitely important problem to address. A lot of vaadin apps use addons so adoption of vaadin 7 will be slow if addons aren’t updated. Hopefully the respective authors take note and convert them. Maybe vaadin can send a mail to developers urging them to convert. I don’t know exactly how hard they are to convert as I haven’t tried it yet but I have confidence that vaadin will probably provide an intuitive conversion doc and process.
There’s a migration guide
here
, scroll down to “Migration Steps for Add-ons”. A functioning migration (not taking full advantage of new features) isn’t very difficult to achieve. I guess the amount of migrated add-ons will increase faster now that the beta version is out and the APIs should remain quite stable.
