---------------------------------------------------------------
Ok the issue is very likely in the XHRRequestLevel2 code
if (this._context._mfInternal.xhrOp === "multipartQueuedPost") {
ret = new FormData(this._sourceForm);
FormData does not have the getKey Function, we simply have to add a hasKey
function on the FormData class!

> Key: MYFACES-4672
> URL: https://issues.apache.org/jira/browse/MYFACES-4672
> Project: MyFaces Core
> Issue Type: Bug
> Affects Versions: 2.2.16
> Reporter: Volodymyr Siedlecki
> Assignee: Werner Punz
> Priority: Major
>
> This affects 2.2 which I know is out of date, but I have a user of MyFaces
> 2.2 who needs this bug fixed.
> I ported MYFACES-4606 to 2.2 here:
> [https://github.com/apache/myfaces/pull/647]
> 4606 was applied to 2.3, so I applied the same fix to 2.2. However, I didn't
> realize that _AjaxRequestLevel2 was removed from 2.3 in this PR:
> [https://github.com/apache/myfaces/pull/415/files]
> _AjaxRequestLevel2 still exists in the 2.2 codebase.
> This mean that `if(targetBuf.hasKey(identifier))` was called from
> _AjaxRequestLevel2's getFormData which does not decorate the FormData to
> include the hasKey method – thus we get " G.hasKey is not a function".

> This error is reproducible via multi-part form requests that use ajax.
> What is the proper fix here? I'll create a draft PR for what I think is
> correct.
> Thanks!
