Hi guys,
Supposing we've already had an IDL implemented by JS codes, and then
we need to let another C++ class inherit that IDL header. However, in
the C++ implementation, we need to get a context to unwrap some JS
values. As my best understanding, adding a [implicit_jscontext] tag
can let us do so, but that will conflict with the original JS
implementation.
Does anyone know how to deal with this kind of dilemma? Any quick
thought is highly appreciated! Thanks!
Gene
Is there some reason you can't add the implicit context to the original
IDL?
Cheers,

implicit_jscontext makes the IDL cannot be implemented in JS, while we
hope to keep the original JS implementation.
We got an error message looks like: "IDL methods marked with
[implicit_jscontext] or [optional_argc] may not be implemented in JS"
when we try to create a JS implemented instance after adding
implicit_jscontext.
BTW, is nsContentUtils::GetSafeJSContext suitable for this situation?
Thanks,
Patrick
