So the static validation for the following "require at least n" validator works alright, but when AJAX validation is enabled, the error messages are not cleared properly.
I think the issue might be that, while the errors are cleared on the server-side stuff and the JSON array of messages it returns omits the errors for the attributes once conditions are met, the function called to update a field on change, $.fn.yiiactiveform.updateInput(), only updates that single attribute.
Any suggestions? How could I get it to update all the attributes’ messages so the errors are consistent?
