Hi,
I'm writing an XPCOM component in C++. It's using js callbacks defined
as follow in an idl file:
[scriptable, uuid(...)]
interface JSCallback : nsISupports
{
boolean call();
};
In the C++ code, I'm using them as follow:
nsCOMPtr<JSCallback> foundcb;
...
foundcb->Call(&ret);
I can successfully trig the callbacks from the C++ compononent, when
calling it from the main thread.
My problem is that I also have to trig those callbacks in other
threads, created by a third party dll that I'm also using
successfully. Those calls end up in the following js error:
Error: [Exception... "'Permission denied to get property Function.__parent__'
when calling method: [JSCallback::call]" nsresult: "0x8057001e
(NS_ERROR_XPC_JS_THREW_STRING)" location: "<unknown>" data: no]
The callback objects are proxified in the main thread as follow:
foundproxy->GetProxyForObject(NS_PROXY_TO_MAIN_THREAD,
JSCallback::GetIID(),
foundcb,
NS_PROXY_SYNC|NS_PROXY_ALWAYS,
getter_AddRefs(foundcbproxy));
I'm then using the callback like that:
foundcbproxy->Call(&ret);
Any idea of the source of the error ?
Thanks a lot for your reply.
-AJ
