It's been a while since this topic was brought up, but I've been able to verify that wicket 1.3 *breaks* applications using the prototype javascript library. Anytime I enable "strip javascript comments and whitespace", or configure my app in "DEPLOYMENT" mode, I get tons of javascript errors.
I've filed an issue in JIRA and attached a sample project that exhibits the issue. https://issues.apache.org/jira/browse/WICKET-987 My recommendation would be to use an "official" javascript minification library, but whatever it takes to get this fixed ASAP would be awesome.
