Chris Ligon commented on RF-7921:
---------------------------------

I had a drop down menu in a rich:dataTable and it worked fine (no offset).  But, when I put the rich:dataTable inside of a rich:tab this offset issue presented itself. 

Mano, could you explain a little bit about what this piece of code is doing?  Why are you doing the layer.replace part?  It seems that maybe you are escaping the :, but why is that?

This workaround works to some extent.  The problem is that for another dropdown menu (with sub-menus) outside of the rich:dataTable this script causes errors.  Basically, the menu does not drop down, it's not visible at all.  And, after removing the mouse from over the menu item, I see just below the menu item, "/:/g/:/g".

Is there a way to limit the scope of this script so that it just works on the dropdown menus that need it?

> The popup list of the drop down menu is wrongly positioned when one scrolls the page. It is shown too far below it's anchor point (i.e. it is not directly connected to it's anchor point) - the offset changes on scrolling (i.e. the more one scrools down, the farer below it is shown)
