I'm trying to setup a custom module, with a field group that is set to repeat.
The config for this seems to be fine, but when I try to go manage the module and add a new item into the repeater group, nothing happens when I click the pencil icon to edit the item. I can delete the item via the trash icon, and add a new item-- but I cant seem to edit it.
There is also an "Undefined" that appears, which I'm not sure where it is coming from.
I just wanted to point out that your module's code doesn't have an effect on the editor options. What happened was most likely caused by a the server serving a bad version (like in between cache), your browser not processing things correctly, or your internet speed causing a bad load. This type of thing will happen to me from time to time as well, in most cases a hard refresh will solve the problem. Other times I have to switch to an incognito window to get a fresh work browser, and the rest of the time you just have to wait it out. I'm glad it sorted itself out.
