Description

In Session.java line 1406 there is a test for deciding whether to set the page as an attribute to the session. The test reads:
if (page.isStateless())

Page does not override isStateless, and the default implementation (in Component) will return true for most pages.
That means pages are not re-added to the session after being changed and this in turn breaks clustering (the results are most vivid when using a non-sticky load balancer).

The fix is to change line 1406 to:

if (page.isPageStateless())

Maybe this is a typing mistake in the original code?
