Hello everyone!
I have a Vaadin application embedded on a web page using [font=courier new]
[/font] element, set according to the [url=https://vaadin.com/book/vaadin7/-/page/advanced.embedding.html#advanced.embedding.div]
"11.2.1. Embedding Inside a div Elemen"
[/url]. Originally the app was written for Vaadin 7.1.15 and worked correctly. But when Vaadin's version is changing to number >= 7.2.0 (up to 7.3.8), the app has unexpected behaviour.
I’ll try to decsribe when it happens:
- A user just logged in on a web site and moved to a web page with the embedded app.
- The page is fully loaded and the app too.
- When the user click on some UI control element of the app then the “Session Expired” system message appears immediately.
- The user can’t do anything except click on the message to reload the page.
- After reloading the app works correctly until app server reloaded (I use Tomcat 7).
Some notes:
- There are no problems when an [font=courier new]
