Re: Error with tree component with 1.5.2
@Martin: It's on FireFox also.
I don't thimk it's an serialization issue because it works fine with an
older Wicket release. The error occurs on expanding and collapsing single
nodes in the tree (inside the updateTree(target) method).

One new hint concerning the error messages. If I use the Tree class instead
of AbstractTree and set the linktype after constructing the tree, the
message doesn't appear any more but the tree component slows down extremely!
...
tm = createTreeModel(animals);
tree = new CdTree("tree", tm);
tree.setRootLess(true);
* tree.setLinkType(LinkType.REGULAR);*
tree.getTreeState().collapseAll();
testForm.add(tree.setOutputMarkupId(true));

Hi,
I have Maven-ized your quickstart app in the ticket because I don't
use Eclipse WTP.
Unfortunately I wasn't able to reproduce this problem with it.
Please modify it so that it fail.

The same problem occurs if I use a PackageResourceReference as an image model
and try to update it in an AjaxLink. When erasing the toggleIcon component
from the target.add method, the error doesn't occur.
/**

public class ToggleLink extends AjaxFallbackLink<Boolean> {
private static final long serialVersionUID = 1L;
private static final Log LOG = LogFactory.getLog(ToggleLink.class);
private static final PackageResourceReference RES_MAXIMIZED = new
PackageResourceReference(ToggleLink.class,"icon_min_container.gif");
private static final PackageResourceReference RES_MINIMIZED = new
PackageResourceReference(ToggleLink.class,"icon_max_container.gif");
private final Image toggleIcon = new Image("toggleIcon",new
PropertyModel<PackageResourceReference>(this,"imgResource"));
@SuppressWarnings("unused")
private PackageResourceReference imgResource;
private final Component toggleComp;

public ToggleLink(String id, final Component comp) {
super(id);
this.setDefaultModel(new PropertyModel<Boolean>(comp,"visible"));
this.toggleComp = comp;
syncImg();
add(toggleIcon.setOutputMarkupId(true));
}
@Override
public void onClick(AjaxRequestTarget target) {
LOG.debug("toggle ...");
toggleComp.setVisible(!this.getModel().getObject());
syncImg();
LOG.debug("visible: " + toggleComp.isVisible());
target.add(toggleIcon,toggleComp);
}
private void syncImg() {
imgResource = this.getModel().getObject() ? RES_MAXIMIZED :
RES_MINIMIZED;

}
