Yes, this could be the problem. I briefly looked through the code and
(i'm not sure) it seems that avalon components without a lifecycle
interface (threadsafe or poolable) or not treated as SingleThreaded in
the new Spring based container.
In line 106 in XmlConfigCreator class in cocoon core we should change from
} else {
current.setModel(ComponentInfo.MODEL_PRIMITIVE);
}
to
} else {
current.setModel(ComponentInfo.MODEL_PRIMITIVE);
singleton = false;
}
SVN is currently not working, so I can't commit and I have no time to
test :( So if someone else could please do this, would be great.
