package onwake and textlistctrl.setValue(%this);
name of your textlistctrl
Dude, you don't need to package every command. In fact, why are you just restating what Chrono said, but in a more confusing way because you're not even making full sentences that make sense.
If you name the GUI object "TextListCtrl", then doing "TextListCtrl.addRow(%text);" will work without the need for an ID.
