FormData is missing overloading append methods (Blob/File)

dankurka commented 9 years ago

Originally reported on Google Code with ID 8021

Found in GWT Release:
GWT 2.4.0, 2.5.0

Detailed description (please be as specific as possible):

According to the W3C standard FormData is supposed to have 2 append functions (http://www.w3.org/TR/2010/WD-XMLHttpRequest2-20100907/#the-formdata-interface):

interface FormData {
  void append(DOMString name, Blob value);
  void append(DOMString name, DOMString value);
};

Currently in elemental the interface looks like this:

public interface FormData {
    void append(java.lang.String s, java.lang.String s1, java.lang.String s2);
}

Therefore it is not possible to upload files using the FormData object.

Workaround if you have one:

Extends JsFormData class and add missing append method:

public class ExtJsFormData extends JsFormData {
  protected ExtJsFormData() {}

  public final native void append(String name,Blob file,String filename) /*-{
     this.append(name,file,filename);
  }-*/;
}

I don't mind to submit a patch however AFAIK the GWT code in the Elemental library is
autogenerated from Webkit's IDL files. So I am not sure how to proceed here best ?
Re-run it and then submit the changes ?

I'm struggling with this too and elemental related issues. Will be this fixed in future
GWT versions? (as all the elemental issues are old..)
