Big problem Liferay and Vaadin theme use


I just want to set a Theme for my portlet in Liefray, but the presentation of the theme is incorrect.

In the first figure I set setTheme(“reindeer”). Behind the reindeer theme is the standard liferay theme.

In the second Theme I set no theme and the presentation of the theme is okay. But I want to use my own theme(reindeer).

Is this a known problem or am I the only one?

Does anyone have any idea how can I fix it?

I added the “testTheme-portlet.war”. Please try it !!
