#3 Cant bind to date property in JCalendarCombo

[Anonymous]

With groovy swingBuilder if I wrote "bean(model, startDate: bind { startDateWidget.date })". it does not work.
It looks like no event fired to notify date change.
but it works that way "bean(model, startDate: bind { startDateWidget.selectedItem; startDateWidget.date })"
startDateWidget is an instance of JCalendarCombo
