ISessionListener#onUnbound(String)

[Martin Grigorov]

Hi,

Do you think the following improvement should be made for Wicket 7:

diff --git i/wicket-core/src/main/java/org/apache/wicket/Application.java

 }

It is a minor improvement to make ISessionListener more consistent with
IApplicationListener - one method for create and another for destroy.
