Hi all.
After upgrading from Vaadin 7.1.14 to 7.2, I noticed that the sessions keep expiring after some minutes (which didn’t happen in 7.1.14), even with the browser window open.
This is my web.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<web-app>
<context-param>
<param-name>productionMode</param-name>
<param-value>true</param-value>
</context-param>
<servlet>
<servlet-name>ReportMachine servlet</servlet-name>
<servlet-class>com.marcozanon.reportmachine.AApplicationServlet</servlet-class>
<init-param>
<param-name>UI</param-name>
<param-value>com.marcozanon.reportmachine.AApplicationCore</param-value>
</init-param>
<init-param>
<param-name>closeIdleSessions</param-name>
<param-value>true</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>ReportMachine servlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
<session-config>
<session-timeout>2</session-timeout>
</session-config>
<context-param>
<param-name>heartbeatInterval</param-name>
<param-value>30</param-value>
</context-param>
</web-app>
Is there anything I must do? or is it a bug?
Thanks for your help,
Marco
