setDateFormat giving wierd results

I have a grid initialised via XML as each row has different cell types. 2 of the Cells are set up as type dhxCalendar.

I have tried to set the grid’s setDateFormat to ‘%d %M %Y’. However this gives me the full Month Name rather than the abbreviated name. If I change %M to %F then only an ‘F’ is output.

I have also tried to setDateFormat for the Calendar object as well to ‘%d %M %Y’ but that doesn’t seem to have any effect on the way the info is displayed in the Grid Cell after being selected from the Calendar.

I am currently using dhtmlx Pro 2.6 version with FireFox 8 on Ubuntu.

Please can you tell me what I’m doing wrong.

Thanks
