Vaadin 7 - Suddenly stopped working

Vaadin 6 / 7 / 8
1

Hello,

My team has been using Vaadin 7 since years for a very basic use case. It has been working fine until yesterday when it suddenly stopped working, saying “Error retreiving your subscription key from the server”. We are NOT using a paid subscription.

Has there been a recent change in free support for vaadin 7? Please let us know.

Adding the vaadin dependencies we are using in our Java build.gradle file below :

“org.vaadin.addons:vaadin-combobox-multiselect:1.1.14”
“org.vaadin.addons:exporter:0.0.6”
“org.vaadin.addons:dcharts-widget:1.7.0”
“com.vaadin.external.gwt:gwt-servlet:2.7.0.vaadin3”

Thanks

Hi,

Thanks for the reply.

I checked the dependencies and found out that it is defaulting to 7.7.23 automatically, even though i am forcing a lower version in build.gradle

Hi,

Found the root cause.

Plugin “fi.jasoft.plugin.vaadin” was causing the issue of pulling the newer version.
Downgrading the plugin version fixed the issue.

Thanks,
