There may be other/better ways, but what I did was this:
class MyTree extends Tree
{
private TreeModelProvider m_provider;
...
@Override
protected void junctionLinkClicked( DefaultMutableTreeNode node )
{
// Keep the functionality of the super class, it is what we want
super.junctionLinkClicked( node );
if( isExpanding( node ) )
{
TreeModel newModel = m_provider.expandNode( node );
if( null != newModel )
setTreeModel( newModel );
expandNode( node );
}
else
{
TreeModel newModel = m_provider.collapseNode( node );
if( null != newModel )
setTreeModel( newModel );
expandNodes((DefaultMutableTreeNode)node.getParent());
}
}
...
}
The TreeModelProvider class provides the model for my tree. In this
class, I decide what data I need to load to properly display the tree,
without loading any unnecessary data.
And of course, when adding this tree to my Wicket page, I use:
Tree tree = new MyTree( "tree", provider )
{
private static final long serialVersionUID = 1L;
protected String getNodeLabel( DefaultMutableTreeNode node )
{
final MyTreeNode treeNode = (MyTreeNode)node.getUserObject();
return treeNode.getLabel();
}
};
add( tree );
Good luck!

Re: [Wicket-user] wicket.markup.html.tree.Tree is not suitable for very big tree
I also have a very big tree, and it works just fine. The secret is to load only the data that is displayed. You need to override the Tree class (it is made for this) and implement it so that only the required data is loaded. Good luck!
