Bug 130071 – AX: AccessibilityObject::invalidStatus() is incorrect when aria-invalid="undefined" or whitespace

• Component: Accessibility
• Status: RESOLVED FIXED

[James Craig]

AX: AccessibilityObject::invalidStatus() is incorrect when aria-invalid="undefined"

The when the string value "undefined" is used explicitly, it should be treated the same as ariaInvalid.isEmpty()

    // If 'false', empty or not present, it should return false.
    if (ariaInvalid.isEmpty() || equalIgnoringCase(ariaInvalid, invalidStatusFalse))
        return invalidStatusFalse;

Should be:

    // If 'false', empty or not present, it should return false.
    if (ariaInvalid.isEmpty() || equalIgnoringCase(ariaInvalid, invalidStatusFalse) || equalIgnoringCase(ariaInvalid, "undefined"))
        return invalidStatusFalse;

i don't see undefined listed in the spec
http://www.w3.org/TR/wai-aria/states_and_properties

> Source/WebCore/accessibility/AccessibilityObject.cpp:1534
> +    DEFINE_STATIC_LOCAL(const AtomicString, invalidStatusGrammar, ("grammar", AtomicString::ConstructFromLiteral));

there's been a desire to stop using statics for things like this. so we might as well change this style if we're going to modify this code.

Let's just use

ASCIILiteral("grammar") when necessary.

From http://www.w3.org/WAI/PF/aria/complete#propcharacteristic_value

The "undefined" value, when allowed on a state or property, is an explicit indication that the state or property is not set. The value is used on states and properties that support tokens, and the "undefined" value is a string that is one of the allowed tokens.

we should remove virtual from the method, since subclassers won't override this
