Vaadin configuration changes
Due to a Vaadin update in Magnolia 6.2.20, custom setups require a change in the web.xml configuration file (in a custom webapp’s WAR under the WEB-INF/ directory).
In particular, you should add the following parameters.
<context-param>
<description>Vaadin production mode</description>
<param-name>productionMode</param-name> (1)
<param-value>true</param-value> (2)
</context-param>
<context-param>
<param-name>heartbeatInterval</param-name>
<param-value>90</param-value>
</context-param>| 1 | Ensure the Vaadin productionMode parameter is present. |
| 2 | The value should be true. |
If you don’t set productionMode to true, you’ll receive errors when starting your custom webapp showing that it’s unable to validate your Vaadin subscription.
