Volodymyr Siedlecki commented on MYFACES-4672: ---------------------------------------------- Thanks! I did tried adding the function, but it caused other errors in their application. The XHR did not contain the form data in the request – it was formatted differently. When I decorated the form data object, the request had: {color:#1d1c1d}j_id_a:j_id_d=[object File] j_id_a_SUBMIT=1 javax.faces.ViewState=etXhe99OOEwGmJMwtxyC6OvI0hBYMSNfhRFQFlnPdIp07mF2KWgN0fDLNVqbkvHTdDOAWQ== javax.faces.behavior.event=change javax.faces.partial.event=change javax.faces.source=j_id_a:j_id_d javax.faces.partial.ajax=true javax.faces.partial.execute=j_id_a:j_id_d j_id_a=j_id_a{color} It should look more like this: {color:#cccccc}-----------------------------10818876671980492753015449693{color} {color:#cccccc}Content-Disposition: form-data{color}{color:#6a9955}; name="j_id_a:j_id_d"; filename="1.txt"{color} {color:#cccccc}Content-Type: text/plain{color} {color:#cccccc}1{color} {color:#cccccc}-----------------------------10818876671980492753015449693{color} {color:#cccccc}Content-Disposition: form-data{color}{color:#6a9955}; name="j_id_a_SUBMIT"{color} {color:#cccccc}1 {color} > Uncaught TypeError: G.hasKey is not a function > ---------------------------------------------- > > 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 This affects 2.2 which I know is out of date, but I have a user of MyFaces 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". > [https://github.com/volosied/myfaces/blob/d5d28a0e6cae3ea22e021c64ecf474d6352bf900/api/src/main/javascript/META-INF/resources/myfaces/_impl/xhrCore/_AjaxRequestLevel2.js#L32-L44] > This error is reproducible via multi-part form requests that use ajax. > What is the proper fix here?
