I got a problem with vaadin 7.3 LR 6.2 since I upgrade and use “valo” the styles Are not aply at all even you get only test (see attached picture) were it supouse to be a component (see attached picture) - under tomcat works fine
i follow instructions from https://vaadin.com/book/-/page/portal.liferay.html#portal.liferay.remove
and also try wiith https://vaadin.com/directory#addon/liferay-control-panel-plugin-for-vaadin
It works fine If you deploy using MAVEN with The archetype can be found from Maven central with groupId
com.vaadin
and artifactId
vaadin-archetype-liferay-portlet -
(see https://www.liferay.com/es/web/matti/blog/-/blogs/using-self-contained-approach-to-package-vaadin-portlets ) also you have to copy the theme in /webapp/ROOT/html/VAADIN
but fails If you generate a WAR using export in eclipse (this method was working fine with vaadin 7-2-6)
The problem is that if you do in that way with the “Maven archetype” doesn’t allow you to run the project over standalone Tomcat - that is much faster to test than deploying to LIferay (using WAR / Eclipse Export - testing over Tomcat was working fine)
