Hey,
Since there currently is no cancel/stop facility in Form.Observer, your
only shot is to use some variable accessible by your callback, that
toggles it off after the first shot, e.g.
var formChanged = function() {
if (arguments.callee.notAnymore) return;
// ...
arguments.callee.notAnymore = true;
}
formChanged.prototype.notAnymore = false;
new Form.Observer('formId', 2, formChanged);
(yes, function prototypes can be used to store "function-static"
variables... You'll see this trick here and there in Prototype's source
code).
