Container hierachies aren't serializable

as discussed in the mailing list. As soon as there is a container hierachy the whole picocontainer isnt serializable anymore.

package pico;

import org.picocontainer.MutablePicoContainer;
import org.picocontainer.defaults.DefaultPicoContainer;
import org.picocontainer.tck.AbstractPicoContainerTestCase;
import org.picocontainer.testmodel.DependsOnTouchable;
import org.picocontainer.testmodel.SimpleTouchable;
import org.picocontainer.testmodel.Touchable;

public class ContainerTreeSerialization extends AbstractPicoContainerTestCase
{
protected MutablePicoContainer createPicoContainer()

{ DefaultPicoContainer container = new DefaultPicoContainer(); DefaultPicoContainer child = new DefaultPicoContainer(); child.registerComponentImplementation(Touchable.class, SimpleTouchable.class); child.registerComponentImplementation(DependsOnTouchable.class); container.addChild(child); return container; }

}
