Why are custom bindings needed?

Because we need to get the ScriptExecutionContext and pass it to the FileReader constructor.

Have you tried [CallWith=ScriptExecutionContext] ?

Proposed Patch

Please try this without custom bindings.  You might need to extend [CallWith] to work with constructors.

WebCore/bindings/v8/custom/V8FileReaderCustom.cpp:48
 +          return throwError("DOM object custructor cannot be called as a function.");
Which spec does this text come from?  Is this text localized?  I don't think we should have this random custom text in the bindings.

[Jian Li]

We do not need this bug now since we choose to change the code generator to avoid the custom bindings code.
