@nuxodin the FormSerializer.patterns are meant to be overridden if you need custom behavior in your application. Do not send a pull request for this kind of edit.

There's a couple examples in the API Documentation.

Hyphen example

$.extend(FormSerializer.patterns, {
  validate: /^[a-z][a-z0-9_-]*(?:\[(?:\d*|[a-z0-9_]+)\])*$/i,
  key:      /[a-z0-9_-]+|(?=\[\])/gi,
  named:    /^[a-z0-9_-]+$/i
});

Dot-notation example

$.extend(FormSerializer.patterns, {
  validate: /^[a-z][a-z0-9_]*(?:\.[a-z0-9_]+)*(?:\[\])?$/i
});

---

For your application, it looks like you'll want to do this

$.extend(FormSerializer.patterns, {
  validate: /^[^\[\]]+(?:\[(?:\d*|[^\[\]]+)\])*$/i,
  key:      /[^\[\]]+|(?=\[\])/gi,
  named:    /^[^\[\]]+$/i
});
