           Summary: The "thisObject" parameter to JSEvaluateScript is not
                    used properly
           Product: WebKit
           Version: 525.x (Safari 3.1)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: easco at mac.com


I created some code that tried to use JSEvaluateScript to pass a script to an
object.  My expectation was that the script would be evaluated in the context
of the object passed into the "thisObject" parameter, but I found that the
script is always evaluated in the global context.

For example, I tried to do something like

JSObjectRef myDocumentObject = GetObjectRefForDocument(<some document here>);
JSEvaluateScript(jsContext, myScript, myDocumentObject, ... other args ...);

I wanted to pass the script:

this.addDocumentElement()

but that came up with a type error.  I had to use:

this.documents[0].addDocumentElement()

Which says to me that the script was evaluated in my global context, and not
the context of my document object.
