Hi, I'm not sure if this has been reported before, but I've come across this bug a few times and wanted to share:
After clicking the "Bulk Add / Predefined Choices" button from a multiple choice / radio button form element and then closing the "Bulk Add" thickbox, none of the form edit elements work anymore. I get a javascript error on trying to edit any of the form fields saying "this.anchors is null"
This seems to happen whether I close the thickbox through the "Update" button or the "Cancel" button. It goes away on refreshing the page.
I'm thinking an action that should be firing on closing the thickbox isn't getting triggered or something?
