I hope this makes sense to someone.
I am passing a XULElement as an argument to a XPConnect wrapped Java script
method(nsIDocHandler::attach. It is a component implemented in Javascript)
When I invoke any method (even getAttribute) on the argument, the method
received, I get the following error.
* Call to xpconnect wrapped JSObject produced this error: *
[Exception... "'[JavaScript Error: "e.getAttribute is not a function" {file:
"e:\mozilla\dist\win32_d.obj\bin\components\nsDocHandler.js" line: 53}]'
when calling method: [nsIDocHandler::attach]" nsresult: "0x80570021
(NS_ERROR_XPC_JAVASCR
IPT_ERROR_WITH_DETAILS)" location: "JS frame ::

I am at a complete loss as to what is happening. All I can see in the
javascript interpreter is that at the time this error is reported, the
interpreter is expecting the callee to be an object and it is not. I can
invoke the same getAttribute method at the call site just fine. dump on the
argument displays the object class to be XULElement as expected.
Any insight into what is happening? Are components implemented in Javascript
second class citizens?
Thanks, Praki
