In the Spec2 examples included with Pharo9, in the example for SpListPresenter, when I try to input text in the list filter, I get an error: the debug window says: "Instance of OrderedCollection did not understand #hasElementAt:". The example works correctly in Pharo8.

Is there a workaround to make the example work?

Hi Tau,

The filter that was bundled with the list components is deprecated and should not be used.
Instead, we provide another component with that functionality: SpFilteringListPresenter.

Take a loot there and its examples.

Thank a lot for directing me toward SpFilteringListPresenter.

I think I found a bug in SpFilteringSelectableListPresenter. While using an SpFilteringSelectableListPresenter, if you press ctrl-a, every item in the list will get selected. Then, if you deselect a few items and press ctrl-a again, this time nothing happens. However, if you scroll the list, all the items are suddenly selected again.

This happens because the block that get invoked when ctrl-a is pressed doesn't refresh the presenter. When I changed that block from [ self activateAll ] to [ self activateAll. listPresenter refresh ], the bug disappeared.
