Hi,
richlistitem label is supposed to concatenate label texts contained by item. but it does not work fine. See testcase

I think that the current binding takes care of all the common cases, and you can easily provide your own getter if your binding needs it. Enn, thoughts?
That was my thought too when I saw this bug. But item1 in the testcase seems like it should return a value, no?

Good point. But as neil deakin pointed out, current behaviour is still messy in common case: label are only counted if they are descendant of first node. So, I rewrote my patch by only managing common case.

do not count childs of anonymous content

Punting the review to Enn because I don't have tests enabled.

Why the extra blank line and {}s?

You sliced off the trailing ; by mistake!

Is there a reason to do this?

If so, there's a recently added (but not yet documented) trim() function that trims spaces which you can use instead.

OK, I see that this is just removing the space that was added at the end. It may be easier to just not add the space in that case, but no big deal.

return Array.map(labels, function(aLabel) aLabel.value).join(" ");

Is a new patch necessary ?
It's an easy win in simpler code, so yes please. The only thing I'm not quite sure of is whether we can suppose that JavaScript 1.8 will always be available for this binding, so you might want to use the more conservative

function(aLabel) { return aLabel.value; }

instead of the new shorthand.

patch v3 (uses Array.map)

>+            return Array.map(labels, 
>+                            function(aLabel) { return aLabel.value }

That's some weird wrapping. I'd wrap it like this:
            return Array.map(labels, function(aLabel) { return aLabel.value })
                        .join(" ");
OK, so I lied, I'd actually wrap it like this ;-)
            return Array.map(this.getElementsByTagNameNS(XULNS, "label"),
                             function(aLabel) { return aLabel.value })
                        .join(" ");

Not quite. Please align dots (before map and join) and arguments (this... and function...).
