|
* SUMMARY: Testing scope with nested functions
|
|
*
|
|
* From correspondence with Christopher Oliver <coliver@mminternet.com>:
|
|
*
|
|
* > Running this test with Rhino produces the following exception:
|
|
* >
|
|
* > uncaught JavaScript exception: undefined: Cannot find default value for
|
|
* > object. (line 3)
|
|
* >
|
|
* > This is due to a bug in org.mozilla.javascript.NativeCall which doesn't
|
|
* > implement toString or valueOf or override getDefaultValue.
|
|
* > However, even after I hacked in an implementation of getDefaultValue in
|
|
* > NativeCall, Rhino still produces a different result then SpiderMonkey:
|
|
* >
|
|
* > [object Call]
|
|
* > [object Object]
|
|
* > [object Call]
|
|
*
|
|
* Note the results should be:
|
|
*
|
|
* [object global]
|
|
* [object Object]
|
|
* [object global]
|
|
*
|
|
* This is what we are checking for in this testcase -
