I am using the oneui theme based on Declan Lynch’s tutorial. If I add a Date Time Picker Core Control for a date field it has no css (basically just the text and the rest of the control transparent on the page).
When using the DateTime Picker control on a Xpages using the Server Default theme doesn’t have this issue.
I tried adding manually a Calendar Control using dijit to an oneui based XPage and it had the same problem. But there I was able to set the styleClass to “Tundra” and it worked fine.
I haven’t found a way to do the same to the built in Date Time Picker Core Control.
Any ideas?
