The ComboCharts certainly do support the select event and the #getSelection method (see http://jsfiddle.net/asgallant/rrdhV/ as an example). My guess is that you are using a ChartWrapper here, correct? The ChartWrappers are one layer abstracted from the base chart, and not all events in the base chart bubble up to the ChartWrapper (the select event is one of them), so you have to register the select event on the base chart itself, like this: http://jsfiddle.net/asgallant/rrdhV/1/
