Now I implemented it in that way:
IColumn[] columns = new IColumn[] { new
AbstractPropertyColumn<T>(
new ColumnLocation(Alignment.MIDDLE, 8,
Unit.PROPORTIONAL),
null, id) {
/**
*
*/
private static final long
serialVersionUID = 1L;
@SuppressWarnings("unchecked")
@Override
public String getNodeValue(final
TreeNode node) {
S object = (S)
((DefaultMutableTreeNode) node).getUserObject();
return nodeToString(object);
}
public Component
newCell(MarkupContainer parent, String id,
TreeNode node, int
level) {
return
TreeTable.newTreeCell(parent, id, node, level, new
TreeTable.IRenderNodeCallback() {
private static final
long serialVersionUID = 1L;
public String
renderNode(final TreeNode node) {
return
getNodeValue(node);
}
}, getTreeTable());
}
public IRenderable newCell(TreeNode
node, int level) {
return null;
}
}
};
The corresponding page displays the right amount of cells, but without any
content. What I am doing wrong ? I can't get it...
