Configuring Tree – Defining Node Column
The id of the column that you want to display node labels (or +/- norgie) should be passed to setNodeColumn method
In buildcomponentCOnfig method, builder should call this setter method on TreeConfig
Example:
TreeConfig tree = factory.newTreeConfig();
tree.addComponent(factory.newColumnConfig(NAME, true));
tree.addComponent(factory.newColumnConfig(NUMBER, true));
tree.setNodeColumn(NUMBER);
