Bug 21235 – REGRESSION (r36882-r37006): accessing the red property of an RGBColor throw an exception

• Component: WebCore JavaScript
• Status: RESOLVED DUPLICATE

[Benoit Marchant]

I'm pretty sure it started to happen in Version 3.1.2 (5525.20.1):

	var startTypedValue = startValue.getRGBColorValue(), 
		startR = startTypedValue.red.getFloatValue(1);

startTypedValue is returned fine, but on different calls:
startTypedValue = Object-ID164
startTypedValue.red = undefined

and on a subsequent call:
startTypedValue = Object-ID168
Gianduia.js (line 7)startTypedValue.red = -1041054550
Gianduia.js (line 7)startTypedValue.red.getFloatValue = undefined

It used to work just fine, by comparison in FireFox:
startTypedValue = [object CSSRGBColor]
startTypedValue.red = [object ROCSSPrimitiveValue]
startTypedValue.red.getFloatValue = function getFloatValue() { [native code] }

and in Safari (shipping version)
startTypedValue = Object-ID4
startTypedValue.red = Object-ID5
startTypedValue.red.getFloatValue = function getFloatValue() {
    [native code]
}

Could you please provide a test case, or a link to a page where this problem occurs?

I cannot reproduce this problem from the above description. Also, are you saying that this happens in shipping Safari, and not a nightly build? For nightly builds, this may be related to bug 21241.

I just uploaded a test file showing the problem

You didn't say whether you see this problem with a nightly build, or with shipping Safari/WebKit 3.1.2. I can not reproduce it with shipping Safari/WebKit, so it is probably the same as bug 21241.

the problem happens only with the nightly webkit

This regresses from r36882 to r37006, so it looks like it is a duplicate of bug 21241.
