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're using Liferay as a portal platform and wiki comes as a preinstalled portlet with it. Vaadin itself supports Liferay, so you can develop your portlets as Vaadin applications, and Liferay and Vaadin are technology partners. If you have more questions about integrating Liferay and Vaadin feel free to ask them in the forum, or, if you need significant amounts of assistance, please contact our sales department.
