I think I have to ignore the style complaint about the all caps constants, since those are the names specified in the spec

It seems like this line can fit on the previous line.

Why don't we use nullAtom or emptyAtom instead?

> Source/WebCore/accessibility/AccessibilityNodeObject.cpp:1041
> +        uiActionValue.split(' ', uiActions);

The spec says it's a list of "a set of whitespace-separated tokens". I'm actually surprised that uiactions DOM property isn't DOMTokenList.
Perhaps we should give that feedback to the standards body.  Regardless, we should probably use DOMTokenList's algorithm to split the tokens here.
We also need a test that uses non-space whitespaces.

Can we add a constructor to do this?

You can do both of these things in single line.

Ditto.

> +    RefPtr<UIValueChangeRequestEvent> event = UIValueChangeRequestEvent::create(eventNames().valuechangerequestEvent, eventInit);

Ditto.

I'll inform the committee about this. I'll file another bug about testing uiactions with non space whitespaces

Yes. Will add some new eventInit constructors

If i do that I think the event will be leaked. I'm relying on the static allocation to dealloc the event

FYI, the uiactions IDL attribute is now a DOMTokenList, not a DOMString.
The uiactions content attribute is still a string, of course.

That change will need to come in a different patch, and which point this test will get updated yes

Closing. This approach/spec is no longer being pursued.
