929984 - Object inspector does not show the message property of Error objects unless it was already accessed

Status: RESOLVED DUPLICATE of bug 812764

(DevTools :: Object Inspector, defect)

Description

[Igor Bukanov]

If I type in the console:

console.log(new Error("Hello"))

then it prints the [object Error]. Inspector for it does not show the message property containing the word "Hello".


Similarly, for the following fragment the inspector does not show the message, lineNumber and stack properties:

try { throw new Error("Test 2"); }
catch (e) {
   console.log(e);
}

To force those properties to appear in the inspector I have to access the properties first:

try { throw new Error("Test 2"); }
catch (e) {
   e.message; e.stack; e.lineNumber;
   console.log(e);
}

I think this was fixed with bug 812764. Please retest in Firefox Nightly, and reopen if it doesn't work properly. Thank you!
