Brian Leathem commented on RF-12493:
------------------------------------

Thanks Bernard, your changes are now much more apparent.

To be clear though, the reason you prefer adding the extra attribute over [~lfryc]'s suggestion to change the filter function, is that you still want the filter function, you just want to be able to control if that filter function is applied in responce to the _onlistshow_ event.

Do we need to generalize this approach?  Are there other events that do or could be configured to trigger the application of the filter method?

Perhaps we should instead have an attribute _filterEvent_ that accepts (1 ore more) event names at which the filter function should be applied?  With a reasonable default of course.

> Currently if we want to show all options in rich:select list despite there is already some value typed in the input we have to add this:
> onlistshow="this.rf.component.input.val('');this.rf.component.__updateItems()"
> But this is usage of private method that may be subject on unexpected changes in future releases of RF.
> Add attribute to rich:select that would not filter list onlistshow.
