[Moose-dev] [Roassal] Z-Ordering for ROPopup

Hi, I am building a visualization in which nodes are layout'd one on top of the other (e.g., a tree map). Thus while I place the nodes I incrementally increment a variable (i.e., the level) and set their #zIndex accordingly so that are placed in the correct way. I want my nodes to have a popup, thus I am adding @ ROPopup when I construct the ROElement. Unfortunately the ROPopup, even though I assigned a higher zIndex to it, seems not to obey to the z-ordering. Any help? Thanks in advance, R
