I'm using a ToggleButtonBar with a ViewStack in the classic sense, where ToggleButtonBar.dataProvider = theViewStack. I want to configure what buttons are available to click based on runtime conditions and cannot find any property that makes this possible. What I'd like to do is provide a filterFunction on the ToggleButtonBar.dataProvider but unlike most dataProvider properties in various list-based constructs, ToggleButtonBar.dataProvider is not stored as a filterable collection. My kludge is to call toggleButtonBar.removeItemAt(n) based on the conditions after it's been constructed. It works, but there must be a more elegant way to filter the ButtonBar data provider so various runtime conditions will control which ViewStack views are available to the user. Thanks for your suggestions. Erik Erik J. Thomas | intuit | Email Marketing | Staff Engineer | 650-944-2602 | Boulder, CO
