Note that the DateRangePicker popup auto close without firing the selection event of the comboitem that the user click at.
Found a workaround (make popup the child of highlighted window), implemented in https://github.com/idempiere/idempiere/pull/2400
https://tracker.zkoss.org/browse/ZK-5740
This is a Zk bug (re-produceable for 9.6.4, 9.6.5, 10.0.0 and 10.0.1):
https://zkfiddle.org/sample/n2peoh/7-Can-t-select-comboitem-in-popup-combobox
Workaround is to replace the use of combobox with dropdown listbox.
This is also reproduceable with the following test case:
Open Shipment (Customer) window
Create a new Shipment record
Open the Order lookup
Open the date range picker popup for “Date Ordered <=” field.
Attached is the patch to show the DateRangeButton on RequestWindow panel
