Prior to 33c8ac4 in 1.514, copyButton.js had extraneous quotes, so the ZeroClipboard Stapler adjunct could not be loaded at all. After that, it is loaded, but (I think as a regression from SECURITY-71) just throws a JavaScript error when the button is clicked, as can be seen e.g. from the UI Samples plugin:
Uncaught TypeError: Cannot call method 'getAttribute' of undefined
ZeroClipboard.ready ZeroClipboard.js:245
ZeroClipboard.setHandCursor ZeroClipboard.js:181
(anonymous function) copyButton.js:11
(anonymous function) behavior.js:111
(anonymous function) behavior.js:107
Behaviour.applySubtree behavior.js:93
Behaviour.apply behavior.js:76
(anonymous function) behavior.js:71
window.onload behavior.js:125
Cannot get it to work. While the demo at http://zeroclipboard.org/ is working for me, when I try to load ZC from a Jenkins page, the button simply does nothing when clicked—even when I copy the minimal sample from their site rather than trying to use the more complicated stuff in copyButton.js. Tried upgrading to 1.2.3 without success.
