There is a partial workaround :
in case of the button the context menu can be called by passing the event as parameter instead of using componentcontrol ex:
{code}
 	<h:button value="detached menu error" onclick="#{rich:component('contextMenu2')}.show(event);return false;">

	</h:button>
{code}

plus to avoid javascript error I suggest updating line 52 of contextmenu.js by adding a test for "this.target"
such as :

{code}
if (this.target){
                    var parent = rf.$(this.target);
                    if (parent && parent.contextMenuShow) {
                        parent.contextMenuShow(this, e);
                    }
}
{code}

With all that done, under myfaces, the context menu shows at the mouse pointer but then closes right away because it renders 1 pixel off the mouse pointer and that it auto closes as it should when the mouse is off the menu

to fix this offset is added to the contextmenu tag by adding 
{code}
verticalOffset="-1" horizontalOffset="-1"
{code}

With all that done, under myfaces, the context menu shows at the mouse pointer but then inexplicably closes right away - my guess is that the menu renders 1 pixel off the mouse pointer and that it auto closes as it should when the mouse is off the menu

> Context menu can be used "attached" or not, the code below creates 2 buttons, the 1rt one "attached" works as expected but the 2nd one "detached" doesnt. The context menu appears in a wrong place (myfaces) or not at all (mojarra).
