<method name="hoverCell">
<parameter name="aCell"/>
The following code creates an event where the target ends up being the
<colorpicker>, when we really want it to be the individual <spacer> element that
makes up that particular color cell.
<body><![CDATA[
if (this.isColorCell(aCell)) {
this.resetHover();
aCell.setAttribute("hover", "true");
this.mHoverCell = aCell;
+ var event = document.createEvent('Events');
+ event.initEvent('DOMMenuItemActive', false, true);
+ aCell.dispatchEvent(event);
}
]]></body>
</method>
The screwed up sequence:
nsEventStateManager::DispatchNewEvent() calls
target->HandleDOMEvent(mPresContext, innerEvent, &aEvent, NS_EVENT_FLAG_INIT,
&status);
nsXULElement::HandleDOMEvent() subsequently runs the following lines, which
clear the old event and it's target:
nsIDOMEvent* domEvent = nsnull;
if (NS_EVENT_FLAG_INIT & aFlags) {
aDOMEvent = &domEvent;
Eventually as the event bubbles up, it is retargeted, but never to the correct
original target.
If we call HandleDOMEvent without the NS_EVENT_FLAG_INIT, everything works - but
I'm not sure what side effects that has with freeing memory.
Why is the target set and then subsequently cleared and not reset?

The javascript code above is from my patch for bug 109221, in colorpicker.xml.
Anyay, I have verified that the event is originally targeted on the anonymous
content, but ends up being set on the <colorpicker> instead. GetOriginalTarget()
needs to give me the correct original target.
