Hi Igor & all,
i implemented it the suggested way by using BookmarkablePageLink +
attribute modifier.
For this i havee sub classed the extension tree and have overwritten the
populateTreeItem as followed:
// ------------------------------------------------------------------------
@Override
protected void populateTreeItem(WebMarkupContainer item, int level)
{
if ((item.getModelObject() instanceof
DefaultMutableTreeNode) &&
((DefaultMutableTreeNode)
item.getModelObject()).getUserObject() instanceof IConfigurationPage){
populateMyTreeItem(item, level);
return;
} else
{
super.populateTreeItem(item, level);
return;
}
}
protected void populateMyTreeItem(WebMarkupContainer item, int level)
{
final DefaultMutableTreeNode mutableTreeNode =
(DefaultMutableTreeNode) item.getModelObject();
item.add(newIndentation(item, "indent", (TreeNode)
item.getModelObject(), level));
item.add(newJunctionLink(item, "link", "image",
mutableTreeNode));
MarkupContainer nodeLink = newCustomNodeLink(item,
"nodeLink", (IConfigurationPage) mutableTreeNode.getUserObject());
item.add(nodeLink);
nodeLink.add(newNodeIcon(nodeLink, "icon", mutableTreeNode));
nodeLink.add(new Label("label", new AbstractReadOnlyModel() {
private static final long serialVersionUID = 1L;
public Object getObject(Component c)
{
return renderNode(mutableTreeNode);
}
}));
item.add(new AttributeModifier("class", true, new
Model("row")));
}
protected MarkupContainer newCustomNodeLink(MarkupContainer parent,
String id,
IConfigurationPage page)
{
PageParameters param = new PageParameters();
param.put("configPage", page.getID());
BookmarkablePageLink pLink = new BookmarkablePageLink(id,
ConfigMainPage.class, param);
pLink.add(new AttributeModifier("target", true, new
Model("main")));
return pLink;
}
//------------------------------------------------------------------------
So in this case only the IConfigurationPage nodes will get a different
nodeLink -> newCustomNodeLink.
This works so far pretty good - the only problem is now when i click on
a custom link and afterwards on a plus or minus i receive the following
exception:
//-------------------------------------------------------------------------------------------------------------------------------------------------

Do you know how i can avoid this?
Thanks in advance!
