Problem reported by customer:
With selectInputDate encapsulated within:
<ice:panelGroup id="tabSetTabs">
<ice:panelTabSet id="mesOnglets" title="Details">
<ice:panelTab label="Test">
<ice:selectInputDate id="testCalendar" renderMonthAsDropdown="true"
renderYearAsDropdown="true" renderAsPopup="true"/>
</ice:panelTab>
</ice:panelTabSet>
</ice:panelGroup>
and having renderMonthAsDropdown="true" renderYearAsDropdown="true" (as shown above). Then, clicking on another month or on a year => close the Calendar => user can't change month or year.
Please try to recreate this issue.
