214611 - Same strict warning displayed 12 times

Status: VERIFIED DUPLICATE of bug 104549

(Core Graveyard :: Error Console, defect)

Description

[zack-weg]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5b) Gecko/20030730
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5b) Gecko/20030730

The same strict warning is displayed 12 times.


Reproducible: Always

Steps to Reproduce:
1. Enable JavaScript strict warnings.
2. Open JavaScript Console.
3. Load testcase.

Actual Results:  
Same warning appears 12 times.
Every time you click the "test" button you will get another 12 warnings.


Expected Results:  
Only 1 warning per reference to an undefined property.


Note: If you uncomment the absolutely useless declaration |var x;|, you get only
one warning related to the undefined property, but 12 warnings for reference to
undefined QueryInterface. However, if you add more references to undefined
properties, you get another 12 warnings, which are related to QueryInterface
iff a global variable is declared.

Behavior in 1.4 is the same, but there are no warnings related to
QueryInterface. In 1.3 there was no such bug, IIRC.

This bug makes strict mode quite unusable because it slows Mozilla down and
finding important warnings becomes very difficult, especially if you're inside
a loop.

I have Mozilla 1.4 (Mozilla/5.0 (Windows; U; Windows NT 5.0; cs-CZ; rv:1.4)
Gecko/20030624) and I can confirm this. But I see the warning message 13x.

I can confirm this for almost every strict waning message I have seen in the
JS-console. Strict mode is less usefull know.

For comparison you can look at http://www.czilla.cz/ <- there should be 2 strict
warning messages about document.all but every is here 13x

Yes, it's a dupe. I didn't find the other bug because of the wrong component.
