Oracle Forms 12c how to show daycharacters in headstart datepicker.
After migrating forms from Oracle 10G to Oracle 12C the characters in the headstart datepicker are not shown above the daynumbers (see pictures below)
The headstart datepicker is a standard object in the library qmsolb65gui.olb called QMSSO$calendar.
Using form builder 10G you can drag the object from the object library to an empty form module. Choose for subclass the object. A canvas CALENDAR is made with 2 rectangle graphics and 7 text graphics. Each text graphic is one of the characters of the weekdays.
Using form builder 12C you can do the same, but then a canvas CALENDAR is made with 9 rectangle graphics.
If you choose 'copy' in stead of 'subclass' after dragging the object to the form module then the right canvas is made, with 2 rectangles en 7 text items.
Is this a known problem and is there any solution for this problem?
Thanks in advance.
