GAE serialization issues with Vaadin charts

Flow
1

Hi,

We have a working Vaadin 6 application which uses Vaadin Charts (a single chart); when trying to deploy it to GAE, we get ‘out of sync’ issues, and the attached stack trace at the moment we want to display the chart. There are no issues running in Tomcat.

We don’t call the PartialPaintChecker interface directly.

any clues on what is the problem? is Vaadin Charts compatible with GAE?

thanks,

Fixed this issue by modifying the vaadin-charts source code to extend/implement Serializable where missing. With those changes, it seems Vaadin Charts is perfectly compatible with GAE.

Not sure how to contribute those changes to the official code?

thanks,
