Use Vaadin Chartjs on a HA environment

[scipionyx]

HI,

When trying to deploy an application on a HA environment, Vaadin-Chartjs configuration objects complain about non-serializable objects.

Caused by: org.springframework.core.serializer.support.SerializationFailedException: Failed to serialize object using DefaultSerializer; nested exception is java.io.NotSerializableException: com.byteowls.vaadin.chartjs.config.BarChartConfig

Is the system prepared for view serialization ?

Fixed, tested on a deve environment, trying tonigh on a near production with 3 nodes. If it works there i will try to send a push request

Hi, I have just confirmed, the changes on the code have fixed the problem for a deployment on a HA environment using Docker nodes.

I need some help on pushing the changes, for some reason I don't have the permission for pull request

Hi,

it looks like you just did create a branch (feature/feature_42) in your fork (scipionyx/vaadin-chartjs) but didn't pushed something there.

Please check where your remotes pointing to and push your commits to your feature branch.

git remote -v

After that github will let you create the PR.
