multipledatepicker is not working in modal popup
multipledatepicker is not working in the bootstrap modal popup.
Datepicker is open but the selection is not filling the dates in the text element.
And showing the error in inspect element as below.
jquery-ui.multidatespicker.js:487 Uncaught RangeError: Maximum call stack size exceeded

This is an old issue, so probably irrelevant by now.
Anyway, was the issue happening also with the standard jQuery UI datepicker?
