Summary REGRESSION: Scriptable plugin hides properties of OBJECT element
mitz
Reported 2005-10-12 15:49:22 PDT
A plugin that implements a scriptable object in ObjC can cause all properties of the OBJECT element containing it to be undefined. To reproduce: open the testcase in Safari. It tests for the children property not being undefined. This happens when the plugin does not respond to invokeUndefinedMethodFromWebScript:withArguments:.

Created attachment 4331 [details] proposed patch The bug resulted from the path for bug 4313, specifically the change in RuntimeObjectImp::getOwnPropertySlot. An alternative fix is to undo that change.

Comment on attachment 4331 [details] proposed patch I believe the underlying cause here is that Objective-C "undefined" values are not returned true to isUndefined(). I think we should fix that rather than applying this patch or undoing the change from bug 4313.
