Warning : very low performances with opera !

I just want to warn you about low performances and display problems with opera browser and vaadin.

For example you can try this page : https://vaadin.com/book/-/page/datamodel.properties.html with opera 11.51 on windows 7.

GWT problem ? Vaadin problem ? opera js implementation problem ? i don’t know where is the fault but that break the browser.

Sorry for my english and have a nice day.

Hi,

thanks for reporting this issue. This had actually nothing to do with Vaadin or GWT as the web version of the Book of Vaadin is not implemented using Vaadin. The problem was related to some broken HTML code that made Opera render the whole page using the
Cufón
library (that is supposed to be used only for the headings).

The issue is now fixed and you should be able to enjoy the Book of Vaadin with Opera again. :slight_smile:
