chowky 一向都覺得 invalidateList and invalidateDisplayList 好似一樣的，近來看到一個post，終於有人解答這個問題，（不過尚有很多有待解決）。

invalidateList tells the component that the data has changed, and it needs to reload it and re-render it.

invalidateDisplayList tells the component that it needs to redraw itself (but not necessarily reload its data).

簡單直接。所以下以要update　data　的話，就要用invalidateList。

（之前通常兩個都set　＝。＝‘‘，要改改習慣）
