UI Builder Calendar Component Problem

[Velma]

UI Builder Calendar Component. Rome, Patch 5 on PDI. Rome, I do not have access to determine in my actual environment. The following behavior is the same and absolutely consistent (multiple repeats) in both:

I add Calendar component to a page—to keep it simple, an entirely vanilla page. To keep it simple, all I do is add an instance of the Calendar component, vanilla configuration, and I save. I Open the page, it looks good and appears to work fine. Back in development, I try to switch to another page, and it says “This page has unsaved changes.” Cancel returns me to the page, but the Save button is not enabled. Save and Continue goes nowhere. Discard will change to a different page—but when I return to the Calendar page, it is a fully corrupted page, no components showing, nothing accessible, just a single diamond where there should be a tree. If it was previously saved, I can restore it going to sys_ux_macroponent (I don’t have access to Revert, but I can edit out the Composition JSON from the history Payload XML, and paste it in, which works)—that gets me back to a working page, but not one with a Calendar component. (I have not tried reverting in PDI, where presumably I could just click the button.)

I can tell from the extensive documentation in the forum that people are able to use this component. If my problem was a permissions issue, it would not occur exactly the same on the PDI. Am I in both places on the same version that wasn’t adequately regression tested, or something about an upgrade glitch? These are the only explanations I can think of. Does this occur for others in Rome Patch 5? Does anyone have a workaround? (I tried clearing the PDI cache after reading about that and that did not help.) Will it get fixed in Rome?—we are unlikely to go to San Diego any time soon. I do not have access to put in a ticket, but I can try to pursue that through my channels. Any suggestions or information would be very welcome.

UPDATE on solution. It is just the "Timeline section" property. You can use the replacement sample I posted above, OR, you can just edit the provided sample (in Rome), either editing all the "content" attributes to an empty string or removing them (and the comma before each of them) entirely. You have to do this before you save the page. Note: I haven't actually tried to do anything with the calendar yet, just gotten to a working sample. I will see if someone has written a great tutorial. 🙂
