Hello,
 
As I reinvestigated into this problem, I might found the problem in the method JspStateManagerImpl$SerializedViewCollection.add(FacesContext, Object):
        public synchronized void add(FacesContext context, Object state)
        {
            Object key = new SerializedViewKey(context);
            _serializedViews.put(key, state);
            _keys.add(key);
 
            int views = getNumberOfViewsInSession(context);
            while (_keys.size() > views)
            {
                key = _keys.remove(0);
                getOldSerializedViewsMap().put(key, _serializedViews.remove(key));
            }
        }
Here the serializedView will be saved. If the number of added views exceed the NUMBER_OF_VIEWS_IN_SESSION_PARAM, the first view get´s removed from the arrayList _keys and from the hashMap _serializedViews and will be put in the getOldSerializedViewsMap().
 
This method will be called twice; once from facelet (ExtendedFaceletViewHandler.renderView) and once from DummyFormUtils.writeDummyForm()
 
So accessing one page causes two entries in _keys and one entry in _serializedViews
 
Also the while-part will be called twice, which means that the second call return null in _serializedViews.remove(key), so a null-value will be tried to put inside the getOldSerializedViewsMap()...
 
Can somebody comprehend this behavior?
 
Could the following be correct hack around this?
 
while (_keys.size() > views)
{
  key = _keys.remove(0);
  Object removedView = _serializedViews.remove(key);
  if( removedView != null )
  {
    getOldSerializedViewsMap().put(key, removedView);
  }
}
But maybe the mistake is, that this method is called twice...?!
 
Cheers,
Roland

Hi!

I have some problems upgrading from 1.1.3-SNAPSHOT-libraries to the latest stable 1.1.3!

Everything was working fine with the old libraries - I've just made some changes in my faces-config.xml like mentioned here:
http://wiki.apache.org/myfaces/Upgrading_to_Tomahawk_1.1.3

What could be wrong here?

Thanks for helping.
