Hello Forum,
get following message
Failed to load the widgetset: ./VAADIN/widgetsets/com.vaadin.DefaultWidgetSet/com.vaadin.DefaultWidgetSet.nocache.js?1443879584867
after project import on Eclipse Mars (latest version).
Project came from Eclipse Juno with Vaadin 7.4.6
Made a clean install with Vaadin 7.5.6 and do not have own widgets.
Cleaned the project, resolved the ivy, cleaned caches…
Sitting here since hours do not know what to do.
Simple new created HelloWorld application in this clean installation works.
But importet project not.
What to do?
Is there no project migration information sheet for tasks like that?
At the moment do not kwow if Eclipse Mars is a recommended version…
