Widgetset not shown correctly

Hello there

I’m trying to figure out what goes wrong when trying to view a widgetset I recently added in our application (specifically the https://vaadin.com/directory/component/wt-pdf-viewer)

The problem is, that the widgetset is not shown correctly: Buttons are there, but the whole UI is messed up. When trying to integrate it in a similar app, everything is fine.

I’m trying to pinpoint what exactly is the problem: if there are no error messages, and the buttons of the widgetset seem to be there, is this more of a theme problem rather than the widgetset itself? Does anyone have any tips what I would check?

I’m using Vaadin 7.6.4 and I’ve also attached a screenshot.

I already tried clean, install. Also checked the content of the widgetset.xml etc.

Many thanks

I think you are on a correct track here, it looks like theme is missing. Try to recompile the theme. Double check from Browser console log if there is error when it tries to load styles.css file, etc.
