No more than 100 features can be selected when the Select widget uses the default action data setting and the data source in the List widget uses the selected features setting.

Workaround

1. Remove the message action from the Select widget.
2. When the 'Action data' in the Select widget and the data source in the List widget are set to the same value, more than 100 features can be selected:
   1. Set both the 'Action data' within the Select widget and the data source of the List Widget to ‘Selected features’.
   2. Set both the 'Action data' within the Select widget and the data source of the List Widget to ‘Default’.
