Description
Since 5.0.18, Tapestry blows up (IllegalStateException) on return from an event handler that invalidates the session AND uses an ASO. I believe this is an unintended consequence of TAP-399.
The workaround is to nullify the ASO, but it's not at all obvious from the exception.
Here's an example. It blows up unless we either:
(a) comment out the first line of onActionFromLogOut() because it references _myASO; or
(b) un-comment the line that sets _myASO to null.
<html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd">
<body>
<a t:type="actionlink" t:id="LogOut" href="#">Log Out</a>
</body>
</html>

void setupRender()
{ _myASO = "Everything's fine"; } void onActionFromLogOut() {
System.out.println("_myASO = " + _myASO + ".");
Session session = _requestGlobals.getRequest().getSession(false);
if (session != null)
}
}
