- The DataSource component can be used separately, instead of passing it to
the DataTable component, you would call the sendRequest method after you do
the setup of the DataSource as you would normally do for the DataTable.
Nevertheless, the DataSource is mostly meant to return a flat array, not a
hierarchical structure as you have. This means that you would have to catch
events or redefine overridable methods to pick the extra data. Your program
would become quite convoluted, not a good thing.
