I was working with validation today and it would have simplified things a bit to have a wrapperClass for the wrapper, in the same way that errors get an errorClass.
Love this plugin, thanks for the hard work you do!
I'm sorry for the lack of activity on this issue. Instead of leaving it open any longer, I decided to close old issues without trying to address them, to longer give the false impression that it will get addressed eventually, especially after several years with no activity. It doesn't mean I'm abandoning the project, just that I'm unable to work through 200+ open issues with the little time I can afford to spend on this project.
To the reporter (or anyone else interested in this issue): If you're still affected by the same issue, please consider opening a new issue, with a testpage that demonstrates the issue with a current version of the plugin. Even better, make an attempt to fix the issue yourself, and improve the project by sending a pull request. This may seem daunting at first, but you'll likely learn some useful skills that you can apply elsewhere as well. And you can help keep this project alive. We've documented how to do these things, too. A patch is worth a thousand issues!
