We recently did an update on our website, http://www.equanet.co.uk with a design refresh and an update to the library of javascript. We upgraded jQuery to 1.3.2, the validator to 1.5.1 and various other libraries and plugins to their latest version.
Doing this seems to have broken the validator, when an invalid value is entered an error class is still added to fields, but an error message doesn't appear in the accompanying label anymore. Worse, submitting invalid forms is no longer blocked. According to Firefox the following exception is thrown: [Exception... "'Syntax error, unrecognized expression: [...@for="email"]' when calling method: [nsIDOMEventListener::handleEvent]" nsresult: "0x8057001e (NS_ERROR_XPC_JS_THREW_STRING)" location: "<unknown>" data: no] Line 0 The @for will be different depending on which form field is invalid. I recognise the problem being the use of @selectors in the code somewhere but don't know enough about the validator plugin source to fix it myself.
