Hi!

I don't know if anyone has pointed this out yet, but there is an error in the the DataAnnotations to JQuery validation mapper. Under the

jQuery.validator.addMethod("regex", ...

there's the following code:

var match = new RegExp(params).exec(value);
    return (match && (match.index == 0) && (match[0].length == value.length));

The problem is that "params" from jQuery has the regex pattern wrapped inside a variable, and the RegExp object requires the pattern itself to be the first argument. This causes the RegExp to search for a single space character " " in the string and report the first one as a match, thereby successfully validating the input if it contains a space, regardless of what the validation pattern actually is.

The fix should be something like:

    var match = new RegExp(params.pattern).exec(value);
    return (match && (match.index == 0) && (match[0].length == value.length));
