Jan Kriesten commented on WICKET-1773:
--------------------------------------
Behavior is reproducable when sessions are invalidated not within wicket but
e.g. Spring Security.
It turns out that DiskPageStore#unbind calls flushPagesToSaveList() which again
tries to write to the no longer existing SessionStore.
Just clearing the list of pages instead of trying to write them solves the
problem:
---8<---
public void unbind(String sessionId)
{
SessionEntry entry =
(SessionEntry)sessionIdToEntryMap.remove(sessionId);
if (entry != null)
{
if (isSynchronous())
{
entry.unbind();
}
else
{
List pages = getPagesToSaveList(sessionId);
if( pages!=null )
pages.clear();
entry.unbind();
pagesToSaveAll.remove(sessionId);
}
}
}

> the wicket app).
