We are using the Reactive OutSystemsUI.DatePicker web block, which uses the private Moment.js script in OutSystemsUI. We want to add additional locales to the same instance of moment the DatePicker uses (e.g. French) so that the Datepicker's formatted date is also localized (month, week, etc), however the script is not available immediately until a screen is loaded that has a Datepicker on it. It also replaces any existing instance of Moment we might have already loaded and configured the first time it loads the OutSystemsUI.Moment script.

Does anyone have any better solutions for localizing the OutSystemsUI.DatePicker with Moment?

For now, I have done a "hack" where on every screen that uses the Datepicker, I set the OnInitialize and OnReady to call an action that replaces the window.moment variable with our own localized Moment instance, and on every DatepickerOnSelect event I re-format the input text with the replaced instance of moment, since the Datepicker saves the OutSystemsUI non-localized instance inside its scope. But this is very hacky and doesn't always work!
